Struct `Parser`

struct Parser { ... }

A regular expression parser.

This parses a string representation of a regular expression into an abstract syntax tree. The size of the tree is proportional to the length of the regular expression pattern.

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

Implementations

`impl Parser`

fn new() -> Parser

Create a new parser with a default configuration.

The parser can be run with either the parse or parse_with_comments methods. The parse methods return an abstract syntax tree.

To set configuration options on the parser, use ParserBuilder.

fn parse(self: &mut Self, pattern: &str) -> Result<Ast, Error>

Parse the regular expression into an abstract syntax tree.

fn parse_with_comments(self: &mut Self, pattern: &str) -> Result<WithComments, Error>

Parse the regular expression and return an abstract syntax tree with all of the comments found in the pattern.
