Module xpct::format

The formatters provided by this crate.

The formatters in this module can be used to implement custom matchers without having to manually implement their formatting logic. You can use these formatters to get pretty formatting for free.

If you’re just writing tests and not writing custom matchers or formatters, you don’t need anything in this module.

The Format::Value of a formatter tells you what failure output it accepts. For example, MismatchFormat can format any matcher that returns a Mismatch.

See Writing Custom Matchers to learn how to implement your own matchers that use these provided formatters.
