Variants

Literal

Fields

id: usize

prefix: Span<Cow<'a, str>>

The full pattern is the prefix (a literal string)

Substring

Fields

id: usize

prefix: Span<Cow<'a, str>>

The prefix is a substring of a larger string or pattern

Regex

Fields

id: usize

prefix: RegexPattern<'a>

The prefix is a regular expression

Dynamic

Fields

id: usize

prefix: Cow<'a, Match<'a>>

The prefix is a match block or substitution The prefix is a match block or substitution
