//! Feature flag definitions for the Lightning protocol according to [BOLT #9].
//!
//! Lightning nodes advertise a supported set of operation through feature flags. Features are
//! applicable for a specific context as indicated in some [messages]. [`Features`] encapsulates
//! behavior for specifying and checking feature flags for a particular context. Each feature is
//! defined internally by a trait specifying the corresponding flags (i.e., even and odd bits).
//!
//! Whether a feature is considered \"known\" or \"unknown\" is relative to the implementation, whereas
//! the term \"supports\" is used in reference to a particular set of [`Features`]. That is, a node
//! supports a feature if it advertises the feature (as either required or optional) to its peers.
//! And the implementation can interpret a feature if the feature is known to it.
//!
//! The following features are currently required in the LDK:
//! - `VariableLengthOnion` - requires/supports variable-length routing onion payloads
//!     (see [BOLT-4](https://github.com/lightning/bolts/blob/master/04-onion-routing.md) for more information).
//! - `StaticRemoteKey` - requires/supports static key for remote output
//!     (see [BOLT-3](https://github.com/lightning/bolts/blob/master/03-transactions.md) for more information).
//!
//! The following features are currently supported in the LDK:
//! - `DataLossProtect` - requires/supports that a node which has somehow fallen behind, e.g., has been restored from an old backup,
//!     can detect that it has fallen behind
//!     (see [BOLT-2](https://github.com/lightning/bolts/blob/master/02-peer-protocol.md) for more information).
//! - `InitialRoutingSync` - requires/supports that the sending node needs a complete routing information dump
//!     (see [BOLT-7](https://github.com/lightning/bolts/blob/master/07-routing-gossip.md#initial-sync) for more information).
//! - `UpfrontShutdownScript` - commits to a shutdown scriptpubkey when opening a channel
//!     (see [BOLT-2](https://github.com/lightning/bolts/blob/master/02-peer-protocol.md#the-open_channel-message) for more information).
//! - `GossipQueries` - requires/supports more sophisticated gossip control
//!     (see [BOLT-7](https://github.com/lightning/bolts/blob/master/07-routing-gossip.md) for more information).
//! - `PaymentSecret` - requires/supports that a node supports payment_secret field
//!     (see [BOLT-4](https://github.com/lightning/bolts/blob/master/04-onion-routing.md) for more information).
//! - `BasicMPP` - requires/supports that a node can receive basic multi-part payments
//!     (see [BOLT-4](https://github.com/lightning/bolts/blob/master/04-onion-routing.md#basic-multi-part-payments) for more information).
//! - `Wumbo` - requires/supports that a node create large channels. Called `option_support_large_channel` in the spec.
//!     (see [BOLT-2](https://github.com/lightning/bolts/blob/master/02-peer-protocol.md#the-open_channel-message) for more information).
//! - `ShutdownAnySegwit` - requires/supports that future segwit versions are allowed in `shutdown`
//!     (see [BOLT-2](https://github.com/lightning/bolts/blob/master/02-peer-protocol.md) for more information).
//! - `OnionMessages` - requires/supports forwarding onion messages
//!     (see [BOLT-7](https://github.com/lightning/bolts/pull/759/files) for more information).
//!     TODO: update link
//! - `ChannelType` - node supports the channel_type field in open/accept
//!     (see [BOLT-2](https://github.com/lightning/bolts/blob/master/02-peer-protocol.md) for more information).
//! - `SCIDPrivacy` - supply channel aliases for routing
//!     (see [BOLT-2](https://github.com/lightning/bolts/blob/master/02-peer-protocol.md) for more information).
//! - `Keysend` - send funds to a node without an invoice
//!     (see the [`Keysend` feature assignment proposal](https://github.com/lightning/bolts/issues/605#issuecomment-606679798) for more information).
