pub struct Parser { /* private fields */ }
Expand description

A convenience parser for regular expressions.

This parser takes as input a regular expression pattern string (the “concrete syntax”) and returns a high-level intermediate representation (the HIR) suitable for most types of analysis. In particular, this parser hides the intermediate state of producing an AST (the “abstract syntax”). The AST is itself far more complex than the HIR, so this parser serves as a convenience for never having to deal with it at all.

If callers have more fine grained use cases that need an AST, then please see the ast::parse module.

A Parser can be configured in more detail via a ParserBuilder.

Implementations

Create a new parser with a default configuration.

The parser can be run with parse method. The parse method returns a high level intermediate representation of the given regular expression.

To set configuration options on the parser, use ParserBuilder.

Parse the regular expression into a high level intermediate representation.
