Struct Options

pub struct Options { /* private fields */ }

Parser configuration, can be used to tune the regex parsing when adding it to the Builder. Every option defaults to false whether through Default or Options::new.

The parser can also be configured via standard regex inline flags.

Implementations

impl Options

pub fn new() -> Self

Create a new options object.

pub fn case_insensitive(&mut self, yes: bool) -> &mut Self

Configures case-insensitive matching for the entire pattern.

pub fn dot_matches_new_line(&mut self, yes: bool) -> &mut Self

Configures . to match newline characters, by default . matches everything except newline characters.

pub fn ignore_whitespace(&mut self, yes: bool) -> &mut Self

Configures ignoring whitespace inside patterns, as well as # line comments (“verbose” mode).

Verbose mode is useful to break up complex regexes and improve their documentation.

pub fn multi_line(&mut self, yes: bool) -> &mut Self

Configures multi-line mode. When enabled, ^ matches at every start of line and $ at every end of line, by default they match only the start and end of the string respectively.ca

pub fn crlf(&mut self, yes: bool) -> &mut Self

Allows \r as a line terminator, by default only \n is a line terminator (relevant for Self::ignore_whitespace and Self::multi_line).

Trait Implementations

impl Default for Options

fn default() -> Options

Returns the “default value” for a type.

impl From<&Options> for Parser

fn from(_: &Options) -> Self

Converts to this type from the input type.

impl From<Options> for Parser

fn from(opt: Options) -> Self

Converts to this type from the input type.
