To support route blinding, we want to split OnionHopData into two separate
structs, one for inbound onions and one for outbound onions. This is because
blinded payloads change the fields present in the onion hop data struct based
on whether we're sending vs receiving (outbound onions include encrypted blobs,
inbound onions can decrypt those blobs and contain the decrypted fields
themselves).
In upcoming commits, we'll add variants for blinded payloads to the new
InboundPayload enum.
Javadocs refuse unicode and as our rustdocs get copied over to Java
bindings (and thus get run through javadocs) we can't have unicode
in our rustdocs.
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.
This is actually a valid response in some cases, at least for the
`gettxout` command, where `null` is returned if no corresponding
UTXO was found, but the command otherwise succeeded.
Makes it easier to add new arguments without a ton of resulting test changes.
Useful for route blinding testing because we need to check for malformed HTLCs,
which is not currently supported by reconnect_nodes. It also makes it easier to
tell what is being checked in relevant tests.
This gives people more freedom with the channel monitors. For Mutiny
this would be nice for us to be able to create copies of them and pass
aorund in memory without having to serialize until we actually want to.

Small bugfix from Matt Corallo <git@bluematt.me>
This should at least marginally more aggressively target things
which are more likely to have changed in CI, making `ci-tests.sh`
more useful as a "default" script for developers to run locally.
While this is generally uneccessary as users set the `no-std` or
`std` features on the `lightning` crate directly, having this
allows `lightning-background-processor` to be built by itself
without extra dep lines. Specifically, the bindings are moving to
using the `-Z avoid-dev-deps` option, which now causes
`lightning-background-processor` to fail to build directly.
Previously, we barely gave any hints why we excluded certain hops during
pathfinding. Here, we introduce more verbose logging by a) accounting
how much candidates we ignored for which reasons and b) logging any
first/last/blinded hops we end up ignoring.
Fixes#1646.
As `RouteParameters` are not included anymore in
`Event::PaymentPathFailed` since 0.0.115, and we don't give value/payee
as immediate arguments to `find_route` anymore.
A channel's `short_channel_id` is currently only set when the funding
transaction is confirmed via `transactions_confirmed`, which might be
well after the channel initally becomes usable, e.g., in the 0conf case.
Previously we would panic due to a reachable `unwrap` when receiving a
counterparty's `announcement_signatures` message for a 0conf channel
pending confirmation on-chain.
Here we fix this bug by avoiding unsafe `unwrap`s and just erroring out
and ignoring the announcement_signatures message if the `short_channel_id`
hasn't been set yet.
While bindings should probably be able to figure out that this is
the same type as `Self`, for now we simply swap the type to make
the bindings generator have an easier go of it.
The bindings are being updated to consider all traits even if the
trait itself is no-export, which causes issues generating code
around the `Duration` impl here.
We missed one method that now cannot be bindings exported - the
`payment_paths` method, as it returns a slice of objects, which
cannot be supported in bindings.
In bindings we can't practically pass a mutable PSBT, and instead
need to pass an owned transaction and have the sign method return a
signed copy. We do this here for all build modes as its not a
material API change for Rust users.
