    fn at_most(&self) -> Option<usize>;
}

Expand description

Trait used to specify how many times a parser should run.

The following types implement this trait:

usize (e.g. 8): Run the parser 8 times.
RangeFrom (e.g. 4..) Run the parser at least 4 times (maybe more).
RangeInclusive (e.g. 3..=7) Run the parser at least 3 times, but no more than 7 times.
RangeToInclusive (e.g. ..=4) Run the parser at most 4 times (maybe less, even 0).

Required Methods§

The minimum amount of times the thing should be repeated

The maximum aount of times the thing should be repeated. If it is unbounded, this will return None

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
