Macro assert_matches_as_result

macro_rules! assert_matches_as_result {
    ($($arg:tt)*) => { ... };
}

Assert expression matches a case.

• If true, return Result Ok(()).

• Otherwise, return Result Err with a diagnostic message.

This macro provides the same statements as assert_matches, except this macro returns a Result, rather than doing a panic.

This macro is useful for runtime checks, such as checking parameters, or sanitizing inputs, or handling different results in different ways.
