Struct rec::Ch

pub struct Ch<'a> { /* fields omitted */ }

Represents a character that can match one or more characters.

Methods

impl<'_> Ch<'_>

pub const fn any() -> Ch<'static>

Creates a Ch that matches any character other than a newline.

Examples

use rec::{Ch, Element};

assert_eq!(Ch::any().into_rec(), String::from(".").into_rec());

pub const fn alpha() -> Ch<'static>

Creates a Ch that matches any alphabetic character.

Examples

use rec::{Ch, Element};

assert_eq!(Ch::alpha().into_rec(), String::from("[[:alpha:]]").into_rec());

pub const fn alphanum() -> Ch<'static>

Creates a Ch that matches any alphabetic or numerical digit character.

Examples

use rec::{Ch, Element};

assert_eq!(Ch::alphanum().into_rec(), String::from("[[:alnum:]]").into_rec());

pub const fn digit() -> Ch<'static>

Creates a Ch that matches any numerical digit character.

Examples

use rec::{Ch, Element};

assert_eq!(Ch::digit().into_rec(), String::from(r"\d").into_rec());

pub const fn whitespace() -> Ch<'static>

Creates a Ch that matches any whitespace character.

Examples

use rec::{Ch, Element};

assert_eq!(Ch::whitespace().into_rec(), String::from(r"\s").into_rec());

pub const fn start() -> Ch<'static>

Creates a Ch that matches with the start of the text.

Examples

use rec::{Ch, Element};

assert_eq!(Ch::start().into_rec(), String::from("^").into_rec());

pub const fn end() -> Ch<'static>

Creates a Ch that matches with the end of the text.

Examples

use rec::{Ch, Element};

assert_eq!(Ch::end().into_rec(), String::from("$").into_rec());

pub fn sign() -> Ch<'static>

Creates a Ch that matches with the sign character of a number.

Examples

use rec::{Ch, Element};

assert_eq!(Ch::sign().into_rec(), String::from(r"[+\-]").into_rec());

pub fn union(chars: &str) -> Ch

Creates a Ch that matches with any of the given characters.

Examples

use rec::{Ch, Element};

assert_eq!(Ch::union("abc").into_rec(), String::from("[abc]").into_rec());

- is not interpreted as range

use rec::{Ch, Element};

assert_eq!(Ch::union("a-c").into_rec(), String::from(r"[a\-c]").into_rec());
