Struct posix_regex::matcher::PosixRegex

pub struct PosixRegex<'a> { /* fields omitted */ }

A regex matcher, ready to match stuff

Methods

impl<'a> PosixRegex<'a>

pub fn new(branches: Cow<'a, [Vec<(Token, Range)>]>) -> Self

Create a new matcher instance from the specified alternations. This should probably not be used and instead an instance should be obtained from PosixRegexBuilder, which also compiles a string into regex.

pub fn case_insensitive(self, value: bool) -> Self

Chainable function to enable/disable case insensitivity. Default: false. When enabled, single characters match both their upper and lowercase representations.

pub fn newline(self, value: bool) -> Self

Chainable function to enable/disable newline mode. Default: false. When enabled, ^ and $ match newlines as well as start/end. This behavior overrides both no_start and no_end.

pub fn no_start(self, value: bool) -> Self

Chainable function to enable/disable no_start mode. Default: false. When enabled, ^ doesn't actually match the start of a string.

pub fn no_end(self, value: bool) -> Self

Chainable function to enable/disable no_start mode. Default: false. When enabled, $ doesn't actually match the end of a string.

pub fn matches_exact(&self, input: &[u8]) -> Option<Vec<(usize, usize)>>

Match the string starting at the current position. This does not find substrings.

pub fn matches(     &self,     input: &[u8],     max: Option<usize> ) -> Vec<Vec<(usize, usize)>>

Match any substrings in the string, but optionally no more than max

Trait Implementations

impl<'a> Clone for PosixRegex<'a>

fn clone(&self) -> PosixRegex<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
