Parsing and displaying strings is a PITA. `FeeRate` is likely not that
heavily used at the moment and users can always just call
`to_sat_per_kwu()` to format it.
So we can get the `units-1.0-alpha.0` release out the door just remove
the `Display` and `FromStr` impls for now. They can be added back in
later when we have time to get #4339 in.
According to the `serde` docs:
> This is used in error messages. The message should complete the
> sentence “This Visitor expects to receive …”, for example the message
> could be “an integer between 0 and 64”. The message should not be
> capitalized and should not end with a period.
However we have the `expecting` str using the converted type not the
thing the visitor expects.
Use `u64` instead of `FeeRate` since that is what is being parsed. Note
that in `amount` we got it _almost_ correct, subsequent patch will fix
the case.
Adds an implementation of div by NonZeroU64 for Amount, FeeRate, and Weight
types. Also adds a div by NonZeroI64 for SignedAmount. The operations
helps to prevent div-by-zero errors at compile time, rather than runtime.
It follows same pattern as existing div operations
but leverages safety guarantees offered by non-zero types
As per policy in #4090 add a privacy boundary to the `FeeRate` type. Use
the module name `encapsulate` as is done in `amount` - its private so
the name can easily be changed later if needed.
Explicitly do not run the formatter or update rustdoc column width so
that review is easier.
Structs had various phrasings of titles.
Make the wording consistent by concisely stating what it is, instead of
what it does.
Make the wording of all error structs consistent.
Looks like a large diff but if you run
git show --color-moved-ws=allow-indentation-change
you will see that it's 100% moves (though moves of code into the
reference macro). May be easier to just look at src/amount/result.rs
after this; it's pretty short now.
The next commit changes a lot of code, but almost entirely by moving and
indenting it. We try to do the moves here ahead of time, so it the diff
for the next commit will be just deletions and indentations.
f9be30ddbe units: Fix `missing_errors_doc` clippy lint (Jamil Lambert, PhD)
Pull request description:
Change the `missing_errors_doc` clippy lint to `warn`.
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.
One of the TODO lints in Issue https://github.com/rust-bitcoin/rust-bitcoin/issues/3825

We have a bunch of functions and impl blocks scattered around the place
for calculating fee from fee rate and weight.
In an effort to make the code easier to read/understand and also easier
to audit introduce a private `fee` module and move all the code that is
related to this calculation into it.
This is in internal change only.

In preparation for adding a `calc` module use getters and setters in
code that will move to the `calc` module.
(Remember, the `FeeRate` uses an inner sats per kwu value.)

Rust macros, while at times useful, are a maintenance nightmare. And
we have been bitten by calling macros from other crates multiple times
in the past.
In a push to just use less macros remove the usage of the
`impl_from_infallible` macro in the bitcoin, units, and internals crates
and just write the code.
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
The `FeeRate` type wraps a `u64` but the inner value implicitly contains
information about the unit. As such when serializing and deserializing
the unit information is not explicit and if users try to deserialize
with a different unit their code will be silently buggy.
As we do for Amount; add custom serde modules so that users can
serialize in an explicit unit. Furthermore remove the derived impls
forcing users to make the decision. This is as we do for `Amount`.
With this applied one can write
```rust
#[derive(Serialize, Deserialize)]
pub struct Foo {
#[serde(with = "bitcoin_units::fee_rate::serde::as_sat_per_kwu")]
pub fee_rate: FeeRate,
}
```
In preparation for adding `serde` modules to the `fee_rate` module
create a sub directory.
Create a directory and move `fee_rate.rs` to `fee_rate/mod.rs`.
