Struct Parser
pub struct Parser { /* private fields */ }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() -> ParserCreate a new parser with a default configuration.
The parser can be run with either the
parseorparse_with_commentsmethods. The parse methods return an abstract syntax tree.To set configuration options on the parser, use
ParserBuilder.fn parse(&mut self, pattern: &str) -> Result<Ast, Error>Parse the regular expression into an abstract syntax tree.
fn parse_with_comments(&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.
