Trait Kind

pub trait Kind {
    // Required method
    fn kind(&mut self, kind: Kind) -> Option<()>;
}

Combine one or more specs into a range of multiple.

Required Methods

fn kind(&mut self, kind: Kind) -> Option<()>

Set the kind of the spec, which happens only once if it happens at all. In case this method isn’t called, assume Single. Reject a kind by returning None to stop the parsing.

Note that ranges don’t necessarily assure that a second specification will be parsed. If ^rev is given, this method is called with spec::Kind::RangeBetween and no second specification is provided.

Note that the method can be called even if other invariants are not fulfilled, treat these as errors.
