Enum aho_corasick::packed::MatchKind

source ·
#[non_exhaustive]
pub enum MatchKind { LeftmostFirst, LeftmostLongest, }
Expand description

A knob for controlling the match semantics of a packed multiple string searcher.

This differs from the MatchKind type in the top-level crate module in that it doesn’t support “standard” match semantics, and instead only supports leftmost-first or leftmost-longest. Namely, “standard” semantics cannot be easily supported by packed searchers.

For more information on the distinction between leftmost-first and leftmost-longest, see the docs on the top-level MatchKind type.

Unlike the top-level MatchKind type, the default match semantics for this type are leftmost-first.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

LeftmostFirst

Use leftmost-first match semantics, which reports leftmost matches. When there are multiple possible leftmost matches, the match corresponding to the pattern that appeared earlier when constructing the automaton is reported.

This is the default.

§

LeftmostLongest

Use leftmost-longest match semantics, which reports leftmost matches. When there are multiple possible leftmost matches, the longest match is chosen.
