This is a small shim library for passing closures where you need one of the format traits (including [`Binary`] etc.).

[`Binary`]: https://doc.rust-lang.org/stable/core/fmt/trait.Binary.html

## Installation

Please use [cargo-edit](https://crates.io/crates/cargo-edit) to always add the latest version of this library:

```cmd

cargo add fn-formats

```

## Example

```rust

use fn_formats::DebugFmt;

let debug = DebugFmt(|f| {

    f.debug_struct("StructName")

        .field("list", &DebugFmt(|f| f.debug_list().entries(&[1, 2, 3]).finish()))

        .field("set", &DebugFmt(|f| f.debug_set().entries(&[4, 5, 6]).finish()))

        .finish()

});

assert_eq!(format!("{:?}", debug), "StructName { list: [1, 2, 3], set: {4, 5, 6} }");

```

## Versioning

`fn-formats` strictly follows [Semantic Versioning 2.0.0](https://semver.org/spec/v2.0.0.html) with the following exceptions:

* The minor version will not reset to 0 on major version changes (except for v1).  

Consider it the global feature level.

* The patch version will not reset to 0 on major or minor version changes (except for v0.1 and v1).  

Consider it the global patch level.

This includes the Rust version requirement specified above.  

Earlier Rust versions may be compatible, but this can change with minor or patch releases.

Which versions are affected by features and patches can be determined from the respective headings in [CHANGELOG.md](CHANGELOG.md).
