Struct regex_syntax::hir::translate::TranslatorBuilder

pub struct TranslatorBuilder { /* fields omitted */ }

A builder for constructing an AST->HIR translator.

Implementations

impl TranslatorBuilder

pub fn new() -> TranslatorBuilder

Create a new translator builder with a default c onfiguration.

pub fn build(&self) -> Translator

Build a translator using the current configuration.

pub fn allow_invalid_utf8(&mut self, yes: bool) -> &mut TranslatorBuilder

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

When disabled (the default), the translator is guaranteed to produce an expression that will only ever match valid UTF-8 (otherwise, the translator will return an error).

Note that currently, even when invalid UTF-8 is banned, the translator will permit a negated ASCII word boundary (i.e., (?-u:\B)) even though it can actually match at invalid UTF-8 boundaries. This bug will be fixed on the next semver release.

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

Enable or disable the case insensitive flag (i) by default.

pub fn multi_line(&mut self, yes: bool) -> &mut TranslatorBuilder

Enable or disable the multi-line matching flag (m) by default.

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

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

pub fn swap_greed(&mut self, yes: bool) -> &mut TranslatorBuilder

Enable or disable the “swap greed” flag (U) by default.

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

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