Trait IntoRegexCharIter

pub trait IntoRegexCharIter<I> {
    type Iter: Iterator<Item = Result<char, ParameterError<I>>>;

    // Required method
    fn into_regex_char_iter(self) -> Self::Iter;
}

Available on crate feature into-regex only.

Expansion of a Cucumber Expressions AST element into a Regex by producing a chars Iterator following original production rules.

Required Associated Types

type Iter: Iterator<Item = Result<char, ParameterError<I>>>

Type of Iterator performing the expansion.

Required Methods

fn into_regex_char_iter(self) -> Self::Iter

Consumes this AST element returning an Iterator over chars transformable into a Regex.
