Struct `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`

fn new() -> FinderBuilder

Create a new finder builder with default settings.

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.

fn build_forward_owned<B: Into<Box<[u8]>>>(&self, needle: B) -> Finder<'static>

Build an owned forward finder using the given needle from the current settings.

fn build_forward_with_ranker<'n, R: HeuristicFrequencyRank, B: ?Sized + AsRef<[u8]>>(&self, ranker: R, needle: &'n B) -> Finder<'n>

Build a forward finder using the given needle and a custom heuristic for determining the frequency of a given byte in the dataset. See HeuristicFrequencyRank for more details.

fn build_forward_with_ranker_owned<R: HeuristicFrequencyRank, B: Into<Box<[u8]>>>(&self, ranker: R, needle: B) -> Finder<'static>

Build an owned forward finder using the given needle and a custom heuristic for determining the frequency of a given byte in the dataset. See HeuristicFrequencyRank for more details.

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.

fn build_reverse_owned<B: Into<Box<[u8]>>>(&self, needle: B) -> FinderRev<'static>

Build an owned reverse finder using the given needle from the current settings.

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.
