Implementations

impl RegexBuilder

pub fn new() -> RegexBuilder

pub fn to_regex_limited( &self, r: ExprRef, max_fuel: u64, ) -> Result<Regex, Error>

pub fn to_regex(&self, r: ExprRef) -> Regex

pub fn exprset(&self) -> &ExprSet

pub fn json_quote( &mut self, e: ExprRef, options: &JsonQuoteOptions, ) -> Result<ExprRef, Error>

pub fn mk_regex(&mut self, s: &str) -> Result<ExprRef, Error>

pub fn mk_contained_in( &mut self, small: &str, big: &str, ) -> Result<ExprRef, Error>

pub fn mk_contained_in_ast( &mut self, small: &RegexAst, big: &RegexAst, ) -> Result<ExprRef, Error>

pub fn is_contained_in( &mut self, small: &str, big: &str, max_fuel: u64, ) -> Result<bool, Error>

pub fn mk(&mut self, ast: &RegexAst) -> Result<ExprRef, Error>

pub fn is_nullable(&self, r: ExprRef) -> bool

impl RegexBuilder

pub fn unicode(&mut self, unicode: bool) -> &mut RegexBuilder

Enable or disable the Unicode flag (u) by default.

By default this is enabled. It may alternatively be selectively disabled in the regular expression itself via the u flag.

Note that unless utf8 is disabled (it’s enabled by default), a regular expression will fail to parse if Unicode mode is disabled and a sub-expression could possibly match invalid UTF-8.

pub fn utf8(&mut self, utf8: bool) -> &mut RegexBuilder

When disabled, translation will permit the construction of a regular expression that may match invalid UTF-8.

When enabled (the default), the translator is guaranteed to produce an expression that, for non-empty matches, will only ever produce spans that are entirely valid UTF-8 (otherwise, the translator will return an error).

pub fn ignore_whitespace( &mut self, ignore_whitespace: bool, ) -> &mut RegexBuilder

Enable verbose mode in the regular expression.

When enabled, verbose mode permits insignificant whitespace in many places in the regular expression, as well as comments. Comments are started using # and continue until the end of the line.

By default, this is disabled. It may be selectively enabled in the regular expression by using the x flag regardless of this setting.

pub fn case_insensitive(&mut self, case_insensitive: bool) -> &mut RegexBuilder

Enable or disable the case insensitive flag by default.

By default this is disabled. It may alternatively be selectively enabled in the regular expression itself via the i flag.

pub fn dot_matches_new_line( &mut self, dot_matches_new_line: bool, ) -> &mut RegexBuilder

Enable or disable the “dot matches any character” flag by default.

By default this is disabled. It may alternatively be selectively enabled in the regular expression itself via the s flag.

Trait Implementations

impl Clone for RegexBuilder

fn clone(&self) -> RegexBuilder
