Struct Builder

pub struct Builder { /* private fields */ }

Builder for the regexes set

Implementations

impl Builder

pub fn new() -> Self

Instantiate a builder with the default metadata configuration:

• minimum atom length 3

pub fn new_atom_len(min_atom_len: usize) -> Self

Instantiate a builder with a custom minimum atom length. Increasing the atom length decreases the size and cost of the prefilter, but may make more regexes impossible to prefilter, which can increase matching costs.

pub fn regexes(&self) -> &[Regex]

Currently loaded regexes.

pub fn push(self, s: &str) -> Result<Self, ParseError>

Push a single regex into the builder, using the default parsing options.

pub fn push_opt(self, regex: &str, opts: &Options) -> Result<Self, ParseError>

Push a single regex into the builder, using custom parsing options.

pub fn push_all<T, I>(self, i: I) -> Result<Self, ParseError>

where T: AsRef<str>, I: IntoIterator<Item = T>,

Push a batch of regexes into the builder, using the default parsing options.

pub fn build(self) -> Result<Regexes, BuildError>

Build the regexes set from the current builder.

Building a regexes set from no regexes is useless but not an error.
