Change the lint to `warn` in `units/Cargo.toml`.
Allow `missing_errors_doc` in `amount/serde.rs` and `fee_rate/serde.rs`.
Add missing `# Errors` sections to rustdocs where the lint gives a
warning.
There is no reason to ignore the rustdoc example in
`units::amount::serde`. The `as_btc` function requires the `alloc`
features so use `as_sat` in the example instead.
While we are at it clean up the whole block of rustdocs.
Preemptively addressing these mutants before introducing the
cargo-mutants workflow
There are several types of changes:
- Changes that address mutants that were actually missing
- Changes that address test values that cause `cargo-mutants` to think
mutants were missed. For example, `cargo-mutants` will replace the
return values for unsigned integer types with 0 and 1. While a function
might be tested, the test might be testing the function with a call that
results in 0 or 1. When `cargo-mutants` substitutes the function call
with `Ok(1)`, the test will still pass, and it will consider this a
mutant. `cargo-mutants` also replaces operations (+, -, /, %), bitwise
operations (&, |, ^, etc), so an operation such as `3 - 2` results in a
mutant because changing it to `3 / 2` yields the same result
- TODOs to ignore functions/impls in the future
Sometimes JSON parsers may munge floats. Instead of using `f64` we can
serialize BTC amounts as strings.
Includes addition of `alloc` feature gate to `DisplayFullError` to
remove lint warnings when building with `--no-default-features`.
Close: #894
Add a comment to the `serde` module about why we have all the `alloc`
feature gating.
Done as part of #3556 - auditing the whole crate for use of `alloc`
feature.
