Struct memchr::memmem::FinderBuilder

pub struct FinderBuilder { /* private fields */ }

A builder for constructing non-default forward or reverse memmem finders.

A builder is primarily useful for configuring a substring searcher. Currently, the only configuration exposed is the ability to disable heuristic prefilters used to speed up certain searches.

Implementations

impl FinderBuilder

pub fn new() -> FinderBuilder

Create a new finder builder with default settings.

pub fn build_forward<'n, B: ?Sized + AsRef<[u8]>>( &self, needle: &'n B ) -> Finder<'n>

Build a forward finder using the given needle from the current settings.

pub fn build_reverse<'n, B: ?Sized + AsRef<[u8]>>( &self, needle: &'n B ) -> FinderRev<'n>

Build a reverse finder using the given needle from the current settings.

pub fn prefilter(&mut self, prefilter: Prefilter) -> &mut FinderBuilder

Configure the prefilter setting for the finder.

See the documentation for Prefilter for more discussion on why you might want to configure this.
