Struct regex_syntax::ExprBuilder
[−]
[src]
pub struct ExprBuilder { // some fields omitted }
A builder for configuring regular expression parsing.
This allows setting the default values of flags and other options, such as the maximum nesting depth.
Methods
impl ExprBuilder
[src]
fn new() -> ExprBuilder
Create a new builder for configuring expression parsing.
Note that all flags are disabled by default.
fn case_insensitive(self, yes: bool) -> ExprBuilder
Set the default value for the case insensitive (i
) flag.
fn multi_line(self, yes: bool) -> ExprBuilder
Set the default value for the multi-line matching (m
) flag.
fn dot_matches_new_line(self, yes: bool) -> ExprBuilder
Set the default value for the any character (s
) flag.
fn swap_greed(self, yes: bool) -> ExprBuilder
Set the default value for the greedy swap (U
) flag.
fn ignore_whitespace(self, yes: bool) -> ExprBuilder
Set the default value for the ignore whitespace (x
) flag.
fn nest_limit(self, limit: usize) -> ExprBuilder
Set the nesting limit for regular expression parsing.
Regular expressions that nest more than this limit will result in a
StackExhausted
error.
fn parse(self, s: &str) -> Result<Expr>
Parse a string as a regular expression using the current configuraiton.
