pub struct TranslatorBuilder { /* private fields */ }

Expand description

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).

Perhaps surprisingly, when invalid UTF-8 isn’t allowed, a negated ASCII word boundary (uttered as (?-u:\B) in the concrete syntax) will cause the parser to return an error. Namely, a negated ASCII word boundary can result in matching positions that aren’t valid UTF-8 boundaries.

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.
