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

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

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.

Parse the regular expression into an abstract syntax tree.

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