Enum cur::Scent

pub enum Scent {
    Clear,
    Atom(char),
    Range(char, char),
    Union(&'static [Scent]),
    Sequence(&'static [Scent]),
    Repetition(&'static Scent, Cast),
}

Represents a pattern to be matched against.

Variants

Clear

Matches an empty string.

Atom(char)

Matches a single char.

Range(char, char)

Matches any char inclusively between the two given.

Union(&'static [Scent])

Matches any given Scent.

Matches are attempted in the order of the Vec.

Sequence(&'static [Scent])

Matches each given Scent in the order of the Vec.

Repetition(&'static Scent, Cast)

Matches any number of repetitions of the given Scent, including 0.

If the given Cast is [Cast::Minimal], will first match with the fewest number of repetitions. Otherwise, will first match with the greatest number of repetitions.

Methods

impl Scent

pub fn get_possible_detections(
    &self,
    chars: &[char],
    index: usize
) -> Vec<usize>

Return all possible detections of self in starting from index of chars.

A detection is the first index after the match.
