15 months agoDe/serialize custom TLVs on `{Inbound,Outbound}OnionPayload`
Alec Chen [Fri, 19 May 2023 04:16:29 +0000 (23:16 -0500)]
De/serialize custom TLVs on `{Inbound,Outbound}OnionPayload`

When serialized, the TLVs in `OutboundOnionPayload`, unlike a normal
TLV stream, are prefixed with the length of the stream. To allow a user
to add arbitrary custom TLVs, we aren't able to communicate to our
serialization macros exactly which fields to expect, so this commit
adds new macro variants to allow appending an extra set of bytes (and
modifying the prefixed length accordingly).

Because the keysend preimage TLV has a type number in the custom type
range, and a user's TLVs may have type numbers above and/or below
keysend's type number, and because TLV streams must be serialized in
increasing order by type number, this commit also ensures the keysend
TLV is properly sorted/serialized amongst the custom TLVs.

Allow users to provide custom TLVs through `RecipientOnionFields`

Custom TLVs allow users to send extra application-specific data with
a payment. These have the additional flexibility compared to
`payment_metadata` that they don't have to reflect recipient generated
data provided in an invoice, in which `payment_metadata` could be
reused.

We ensure provided type numbers are unique, increasing, and within the
experimental range with the `RecipientOnionFields::with_custom_tlvs`
method.

This begins sender-side support for custom TLVs.

Drop `claimable` from `Balance::claimable_amount_satoshis` fields

In Java/TypeScript, we map enums as a base class and each variant
as a class which extends the base. In Java/TypeScript, functions
and fields share the same namespace, which means we cannot have
functions on an enum which have the same name as any fields in any
enum variants.

`Balance`'s `claimable_amount_satoshis` method aliases with fields
in each variant, and thus ultimately doesn't compile in TypeScript.

Because `Balance::claimable_amount_satoshis` has the same name as
the fields, it's also a bit confusing, as it doesn't return the
field for each variant, but sometimes returns zero if we're not
sure we can claim the balance.

Instead, we rename the fields in each enum variant to simply
`amount_satoshis`, to avoid implying that we can definitely claim
the balance.
