There was a problem hiding this comment.
This will need an additional param for the output to be added.

fixup! [WIP] Implement add_custom_output protocol Just some formattings. [WIP] Continue implementing add_custom_output protocol fixup! [WIP] Continue implementing add_custom_output protocol Some formattings fixup! [WIP] Continue implementing add_custom_output protocol Some formattings Add todo: can this be removed? In this case we did not update the fee rate Fix: mostly using correct variable Impl readable and writable to UpdateAddCustomOutput chore: remove comment This was done now :) chore: some more formattings make tests work We have a test which pretends to add a custom output to the commit transaction. Msgs are being exchanged and commit transactions are being revoked. What is missing is to actually add the output [WIP] Add custom outputs to commit transaction change custom output value to 1234567 to find it easier in logs fixup! [WIP] Add custom outputs to commit transaction pass in a ref of a ref of course :) chore: fix formatting chore: Mark our TODOs with 10101 tag missing docs
To be used in our modified `ldk-sample`.
We are failing to find the route when calling `find_route` i.e. what is commented out with this patch. Since we are not supporting multihop, can we just build the `Route` ourselves?
Subtract the customoutput from local balance

Also, fix all the trivial warnings that were polluting the output of the `cargo check` command.
This information can be used to create transactions that spend from the custom output _before_ the corresponding comit transaction is signed. Also we remove the whole concept of a holding cell for custom outputs because it interfered with this patch and it is unclear if we even need it.
I was debugging against our integration test in `function_tests.rs`.
It is less error prone if the caller only provides the amount they get out of the custom output. The remote party's amount is computed.
It's okay for regtest and testnet.
We were never updating the value of `value_to_self_msat` in `Channel` based on a removed custom output!
