They are intended to be used as a base for building +language-specific bindings, and are thus incredibly low-level and may be difficult to work with +directly. + +In other words, if you're reading this, you're either writing bindings for a new language, or +you're in the wrong place - individual language bindings should come with their own documentation. + +LDK C Bindings +============== + +The C bindings available at include/lightning.h require inclusion of include/rust_types.h first. + +All of the Rust-Lightning types are mapped into C equivalents which take a few forms, with the C +type getting an `LDK` prefix to their native Rust type names. + +#### Structs +Structs are mapped into a simple wrapper containing a pointer to the native Rust-Lightning object +and a flag to indicate whether the object is owned or only a reference. Such mappings usually +generate a `X_free` function which must be called to release the allocated resources. Note that +calling `X_free` will do nothing if the underlying pointer is NULL or if the `is_owned` flag is not +set. + +You MUST NOT create such wrapper structs manually, relying instead on constructors which have been +mapped from equivalent Rust constructors. + +Note that, thanks to the is-owned flag and the pointer being NULLable, such structs effectively +represent `RustType`, `&RustType`, and `Option`. Check the corresponding Rust +documentation for the function or struct you are using to ensure you use the correct call semantics. +The passed struct must match the call semantics or an assertion failure or NULL pointer dereference +may occur. + +For example, this is the mapping of ChannelManager. +```c +typedef struct MUST_USE_STRUCT LDKChannelManager { + /** ... */ + LDKnativeChannelManager *inner; + bool is_owned; +} LDKChannelManager; +``` + +#### Traits +Traits are mapped into a concrete struct containing a void pointer (named `this_arg` and a jump +table listing the functions which the trait must implement. The void pointer may be set to any value +and is never interpreted (or dereferenced) by the bindings logic in any way. It is passed as the +first argument to all function calls in the trait. You may wish to use it as a pointer to your own +internal data structure, though it may also occasionally make sense to e.g. cast a file descriptor +into a void pointer and use it to track a socket. + +This should remind you of a C++ vtable, only written out by hand and with the class only containing +a pointer, instead of the regular class data. + +Each trait additionally contains `free` and `clone` function pointers, which may be NULL. The `free` +function is passed the void pointer when the object is `Drop`ed in Rust. The `clone` function is +passed the void pointer when the object is `Clone`ed in Rust, returning a new void pointer for the +new object. If the `free` pointer is NULL, you will not receive any notification when the trait +object is no longer needed. If the `clone` pointer is NULL, we assume that the trait object may be +`memcpy()`'d to create copies. Note that if you release resources with `free` without implementing +`clone`, you will likely end up with use-after-free bugs (as copies of the original this_arg value +may still exist, unbeknownst to you). + +For example, `LDKSocketDescriptor` is mapped as follows: +```c +typedef struct LDKSocketDescriptor { + void *this_arg; + /** ... */ + uintptr_t (*send_data)(void *this_arg, LDKu8slice data, bool resume_read); + /** ... */ + void (*disconnect_socket)(void *this_arg); + bool (*eq)(const void *this_arg, const void *other_arg); + uint64_t (*hash)(const void *this_arg); + void *(*clone)(const void *this_arg); + void (*free)(void *this_arg); +} LDKSocketDescriptor; +``` + +##### Rust Trait Implementations +Rust structs that implement a trait result in the generation of an `X_as_Y` function, which takes a +C struct wrapping the Rust native object and returns a generated trait object. Such generated +objects are only valid as long as the original Rust native object has not been `free`'d or moved as +a part of a Rust function call (ie continues to be owned by the C struct). For example, to use an +`LDKInMemoryChannelKeys` as a `ChannelKeys`, `InMemoryChannelKeys_as_ChannelKeys` is exposed: + +```c +LDKChannelKeys InMemoryChannelKeys_as_ChannelKeys(const LDKInMemoryChannelKeys *this_arg); +``` + +#### Enums +Rust "unitary" enums are mapped simply as an equivalent C enum; however, some Rust enums have +variants which contain payloads. Such enums are mapped automatically by cbindgen as a tag which +indicates the type and a union which holds the relevant fields for a given tag. An `X_free` function +is provided for the enum as a whole which automatically frees the correct fields for a give tag, and +a `Sentinel` tag is provided which causes the free function to do nothing (but which must never +appear in an enum when accessed by Rust code). The `Sentinel` tag is used by the C++ wrapper classes +to allow moving the ownership of an enum while invalidating the old copy. + +For example, the unitary enum `LDKChannelMonitorUpdateErr` is mapped as follows: +```c +typedef enum LDKChannelMonitorUpdateErr { + /** .. */ + LDKChannelMonitorUpdateErr_TemporaryFailure, + /** .. */ + LDKChannelMonitorUpdateErr_PermanentFailure, + /** .. */ + LDKChannelMonitorUpdateErr_Sentinel, +} LDKChannelMonitorUpdateErr; +``` + +and the non-unitary enum LDKErrorAction is mapped as follows: +```c +typedef enum LDKErrorAction_Tag { + /** .. */ + LDKErrorAction_DisconnectPeer, + /** .. */ + LDKErrorAction_IgnoreError, + /** .. */ + LDKErrorAction_SendErrorMessage, + /** .. */ + LDKErrorAction_Sentinel, +} LDKErrorAction_Tag; + +typedef struct LDKErrorAction_LDKDisconnectPeer_Body { + LDKErrorMessage msg; +} LDKErrorAction_LDKDisconnectPeer_Body; + +typedef struct LDKErrorAction_LDKSendErrorMessage_Body { + LDKErrorMessage msg; +} LDKErrorAction_LDKSendErrorMessage_Body; + +typedef struct LDKErrorAction { + LDKErrorAction_Tag tag; + union { + LDKErrorAction_LDKDisconnectPeer_Body disconnect_peer; + LDKErrorAction_LDKSendErrorMessage_Body send_error_message; + }; +} LDKErrorAction; +``` + +#### Functions +Struct member functions are mapped as `Struct_function_name` and take a pointer to the mapped struct +as their first argument. Free-standing functions are mapped simply as `function_name` and take the +relevant mapped type arguments. + +Functions which return `&OpaqueRustType` and which return `OpaqueRustType` are both mapped to a +function returning an owned wrapper struct. The `is_owned` flag (see above) will be set to indicate +that the pointed-to Rust object is owned or only a reference. Thus, when implementing a function +which Rust will call or calling a Rust function, you should check the Rust documentation for the +function to determine whether an owned or referenced object is expected or returned. + +Similarly, when a function takes an `Option` as a parameter or a return value, the C type +is the same as if it took only `RustType`, with the `inner` field set to NULL to indicate None. For +example, `ChannelManager_create_channel` takes an `Option` not an `LDKUserConfig`, +but its definition is: +```c +MUST_USE_RES ... ChannelManager_create_channel(const LDKChannelManager *this_arg, ..., LDKUserConfig override_config); +``` + +#### Containers +Various containers (Tuples, Vecs, Results, etc) are mapped into C structs of the form +`LDKCContainerType_ContainerElementsZ`. Inner fields are often pointers, and in the case of +primitive types, these may be allocated in C using the system allocator. See [the Rust docs on your +platform's default System allocator](https://doc.rust-lang.org/std/alloc/struct.System.html) for + which allocator you must use. Recursive containers are possible, and simply replace the +`ContainerElements` part with `InnerContainerType_InnerContainerElementsZ`, eg +`LDKCResult_C2Tuple_SignatureCVec_SignatureZZNoneZ` represents a +`Result<(Signature, Vec), ()>`. + +#### Notes +As the bindings are auto-generated, the best resource for documentation on them is the native Rust +docs available via `cargo doc` or [docs.rs/lightning](https://docs.rs/lightning). + +The memory model is largely the Rust memory model and not a native C-like memory model. Thus, +function parameters are largely only ever passed by reference or by move, with pass-by-copy +semantics only applying to primitive types. However, because the underlying types are largely +pointers, the same function signature may imply two different memory ownership semantics. Thus, you +MUST read the Rust documentation while using the C bindings. For functions which take arguments +where ownership is moved to the function scope, the corresponding `X_free` function MUST NOT be +called on the object, whereas for all other objects, `X_free` MUST be used to free resources. + +LDK C++ Bindings +================ + +The C++ bindings available at include/lightningpp.hpp require extern "C" inclusion of lightning.h +and rust_types.h first. They represent thin wrappers around the C types which provide a few +C++-isms to make memory model correctness easier to achieve. They provide: + * automated destructors which call the relevant `X_free` C functions, + * move constructors both from C++ classes and the original C struct, with the original object + cleared to ensure destruction/`X_free` calls do not cause a double-free. + * Move semantics via the () operator, returning the original C struct and clearing the C++ object. + This allows calls such as `C_function(cpp_object)` which work as expected with move semantics. + +In general, you should prefer to use the C++ bindings if possible, as they make memory leaks and +other violations somewhat easier to avoid. Note that, because the C functions are not redefined in +C++, all functions return the C type. Thus, you must bind returned values to the equivalent C++ type +(replacing `LDKX` with `LDK::X`) to ensure the destructor is properly run. A demonstration of such +usage is available at [demo.cpp](demo.cpp). + +Gotchas +======= + +There are a few gotchas around future changes to Rust-Lightning which the bindings may not support. +These include: + * Any trait method which returns a reference to a struct or inner variable cannot be called in + parallel. This is because such functions always return a local variable stored inside the trait, + with a call through a function pointer to get the local variable set correctly. Automatically + generated setter functions have comments describing the potential race conditions in their + definition. + + For example, the `ChannelKeys::pubkeys() -> &ChannelPublicKeys` function is mapped as this: + + ```c + typedef struct LDKChannelKeys { + ... + LDKChannelPublicKeys pubkeys; + /** ... */ + void (*set_pubkeys)(const LDKChannelKeys*); + ... + } LDKChannelKeys; + ``` + * Private and public keys are asserted valid at the FFI boundary. Thus, before passing any + (untrusted) private or public key material across the boundary, ensure that they represent valid + (ie in-range) keys. + +**It is highly recommended that you test any code which relies on the C (or C++) bindings in +valgrind, AddressSanitizer, MemorySanitizer, or other similar tools to ensure correctness.** + +Process +======= + +`genbindings.sh` is currently a catch-all script for bindings - it generates the latest Rust/C/C++ +code for bindings from the rust-lightning source code, builds it, and then runs various test apps. + +Note that after running `genbindings.sh`, if possible, the static lib in target/debug (eg +target/debug/liblightning.a) will be linked with address sanitizer. In order to build against it, +you will need to link with `clang` with `-fsanitize=address` with the same version of LLVM as +`rustc`'s LLVM. If `genbindings.sh` failed to find a matching `clang` or you are building on an +unsupported platform, a warning noting that address sanitizer is not available will be printed. diff --git a/lightning-c-bindings/cbindgen.toml b/lightning-c-bindings/cbindgen.toml new file mode 100644 index 0000000..9480b86 --- /dev/null +++ b/lightning-c-bindings/cbindgen.toml @@ -0,0 +1,555 @@ +# The language to output bindings in +# +# possible values: "C", "C++" +# +# default: "C++" +language = "C" + + + + +# Options for wrapping the contents of the header: + +# An optional string of text to output at the beginning of the generated file +# default: doesn't emit anything +header = "/* Text to put at the beginning of the generated file.
