pub struct Builder { /* private fields */ }
Expand description

A builder for configuring an Aho-Corasick DFA.

This builder has a subset of the options available to a AhoCorasickBuilder. Of the shared options, their behavior is identical.

Implementations

Create a new builder for configuring an Aho-Corasick DFA.

Build an Aho-Corasick DFA from the given iterator of patterns.

A builder may be reused to create more DFAs.

Build an Aho-Corasick DFA from the given noncontiguous NFA.

Note that when this method is used, only the start_kind and byte_classes settings on this builder are respected. The other settings only apply to the initial construction of the Aho-Corasick automaton. Since using this method requires that initial construction has already completed, all settings impacting only initial construction are no longer relevant.

Set the desired match semantics.

This only applies when using Builder::build and not Builder::build_from_noncontiguous.

See AhoCorasickBuilder::match_kind for more documentation and examples.

Enable ASCII-aware case insensitive matching.

This only applies when using Builder::build and not Builder::build_from_noncontiguous.

See AhoCorasickBuilder::ascii_case_insensitive for more documentation and examples.

Enable heuristic prefilter optimizations.

This only applies when using Builder::build and not Builder::build_from_noncontiguous.

See AhoCorasickBuilder::prefilter for more documentation and examples.

Sets the starting state configuration for the automaton.

See AhoCorasickBuilder::start_kind for more documentation and examples.

A debug setting for whether to attempt to shrink the size of the automaton’s alphabet or not.

This should never be enabled unless you’re debugging an automaton. Namely, disabling byte classes makes transitions easier to reason about, since they use the actual bytes instead of equivalence classes. Disabling this confers no performance benefit at search time.

See AhoCorasickBuilder::byte_classes for more documentation and examples.
