This is a fork of the matches crate with an extra unwrap_match! and option_match! macro,
and also better error messages for assert_matches.
The unwrap_match! macro is a general unwrap, used as such:
let output = unwrap_match!(input, AnEnum::Variant(a) | AnEnum::OtherVariant(a) if a < 5 * 2 => a);If it fails, it emits a descriptive error including the pattern and the input,
for this reason input must implement Debug, unless you provide a custom error message
as the last arguments, in the same way you'd use format!.
The option_match! macro is like unwrap_match!, except instead of failing,
it just returns an Option.
let output: Option<_> = option_match!(input, AnEnum::Variant(a) | AnEnum::OtherVariant(a) if a < 5 * 2 => a);The original matches crate would emit horrible errors when assertions failed,
outputting a pattern such as Some(_) as Some ( _ ). This version has properly
formatted errors, so you will never experience this again.
