Trait mockers::MatchArg

pub trait MatchArg<T> {
    fn matches(&self, arg: &T) -> Result<(), String>;
    fn describe(&self) -> String;
}

Argument matcher

Basically it is predicate telling whether argument value satisfies to some criteria. However, in case of mismatch it explains what and why doesn't match.

Required Methods

fn matches(&self, arg: &T) -> Result<(), String>

fn describe(&self) -> String
