Struct regex_syntax::hir::translate::Translator

pub struct Translator { /* fields omitted */ }

A translator maps abstract syntax to a high level intermediate representation.

A translator may be benefit from reuse. That is, a translator can translate many abstract syntax trees.

A Translator can be configured in more detail via a TranslatorBuilder.

Implementations

impl Translator

pub fn new() -> Translator

Create a new translator using the default configuration.

pub fn translate(&mut self, pattern: &str, ast: &Ast) -> Result<Hir, Error>

Translate the given abstract syntax tree (AST) into a high level intermediate representation (HIR).

If there was a problem doing the translation, then an HIR-specific error is returned.

The original pattern string used to produce the Ast must also be provided. The translator does not use the pattern string during any correct translation, but is used for error reporting.
