Enum aho_corasick::packed::MatchKind

pub enum MatchKind {
    LeftmostFirst,
    LeftmostLongest,
    // some variants omitted
}

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

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.

Trait Implementations

impl Clone for MatchKind

fn clone(&self) -> MatchKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MatchKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MatchKind

fn default() -> MatchKind

Returns the “default value” for a type.

impl PartialEq<MatchKind> for MatchKind

fn eq(&self, other: &MatchKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
