Struct fancy_regex::RegexBuilder

pub struct RegexBuilder(_);

A builder for a Regex to allow configuring options.

Methods

impl RegexBuilder

pub fn new(pattern: &str) -> Self

Create a new regex builder with a regex pattern.

If the pattern is invalid, the call to build will fail later.

pub fn build(&self) -> Result<Regex>

Build the Regex.

Returns an Error if the pattern could not be parsed.

pub fn backtrack_limit(&mut self, limit: usize) -> &mut Self

Limit for how many times backtracking should be attempted for fancy regexes (where backtracking is used). If this limit is exceeded, execution returns an error with Error::BacktrackLimitExceeded. This is for preventing a regex with catastrophic backtracking to run for too long.

Default is 1_000_000 (1 million).
