In preparation for emptying the `internal_macros` module move the
`serde_string_impl` and `serde_struct_human_string_imp` macros to the
`serde_utils` module.
Rationale: `internal_macros` stuff can go over in the `internals` crate
now that we have one. The serde macros could go over there but we have a
`serde_utils` module that holds code for implementing serde traits,
these two macros are exactly that.
Recently we moved a few types from `transaction` to `sighash`, while
doing so I erroneously annotated code with the `deprecated` attribute
hoping it would give downstream users a gentle upgrade experience. It
turns out `deprecated` only works on functions.
During that same work, we re-exported from the crate root a bunch of
types from the `sighash` module that probably should not have been
re-exported. We are currently trying to create a nice clean API surface,
in an effort to move in the right direction we should remove the
re-exports and just re-export the `sighash` module.
Try to clean up the sighash export mess by doing:
- Remove the re-exports from the `transaction` module
- Remove crate level re-exports of `sighash` module types
- Re-export `sighash` module
Note, this patch is a breaking API change, justified by the fact that
there is no good way to gently lead downstream when moving types since
types cannot be deprecated with the `deprecated` attribute.
Add a new crate `bitcoin-internals` to be used for internal code needed
by multiple soon-to-be-created crates.
Add the `write_err` macro to `bitcoin-internals`, nothing else.
This patch uses a `path` dependency which means `rust-bitcoin` cannot be
released in its current state, will need to be changed once we release
the `bitcoin-internals` crate on `crates.io`.
Create a directory `bitcoin` and move into it the following as is with
no code changes:
- src
- Cargo.toml
- contrib
- test_data
- examples
Then do:
- Add a workspace to the repository root directory.
- Add the newly created `bitcoin` crate to the workspace.
- Exclude `fuzz` and `embedded` crates from the workspace.
- Add a contrib/test.sh script that runs contrib/test.sh in each
sub-crate
- Fix the bitcoin/contrib/test.sh script
