Struct regex_syntax::hir::translate::TranslatorBuilder
[−]
[src]
pub struct TranslatorBuilder { /* fields omitted */ }
A builder for constructing an AST->HIR translator.
Methods
impl TranslatorBuilder
[src]
pub fn new() -> TranslatorBuilder
[src]
Create a new translator builder with a default c onfiguration.
pub fn build(&self) -> Translator
[src]
Build a translator using the current configuration.
pub fn allow_invalid_utf8(&mut self, yes: bool) -> &mut TranslatorBuilder
[src]
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
[src]
Enable or disable the case insensitive flag (i
) by default.
pub fn multi_line(&mut self, yes: bool) -> &mut TranslatorBuilder
[src]
Enable or disable the multi-line matching flag (m
) by default.
pub fn dot_matches_new_line(&mut self, yes: bool) -> &mut TranslatorBuilder
[src]
Enable or disable the "dot matches any character" flag (s
) by
default.
pub fn swap_greed(&mut self, yes: bool) -> &mut TranslatorBuilder
[src]
Enable or disable the "swap greed" flag (U
) by default.
pub fn unicode(&mut self, yes: bool) -> &mut TranslatorBuilder
[src]
Enable or disable the Unicode flag (u
) by default.
