    Wildcard(Wildcard),
    Character(Character<'a>),
    Group(Vec<Segments<'a>>),
}
Expand description

Atom.

Atoms are the basic building blocks of Segments, representing literals, wildcards, character classes and groups of alternatives. Each Segment contains a set of atoms that define which Specificity the segment has, where specificity is determined by the least specific atom in the segment.

Variants§

§

Literal(&'a str)

Literal, e.g., main.rs

§

Wildcard(Wildcard)

Wildcard, i.e., ?, *, or **.

§

Character(Character<'a>)

Character class, e.g., [xyz].

§

Group(Vec<Segments<'a>>)

Alternate group, e.g., {*.rs,*.md}.
