Struct nommy::text::OneOf

pub struct OneOf<const CHARS: &'static str>(_);

OneOf is a generic type that implements Parse to match one character within the given string

use nommy::{Parse, IntoBuf, text::OneOf};
let mut buffer = "-".chars().into_buf();
let c: char = OneOf::<"-_">::parse(&mut buffer).unwrap().into();
assert_eq!(c, '-');

Trait Implementations

impl<const CHARS: &'static str> Clone for OneOf<CHARS>

fn clone(&self) -> OneOf<CHARS>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<const CHARS: &'static str> Copy for OneOf<CHARS>

impl<const CHARS: &'static str> Debug for OneOf<CHARS>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const CHARS: &'static str> Parse<char> for OneOf<CHARS>

fn parse(input: &mut impl Buffer<char>) -> Result<Self>

Parse the input buffer, returning Ok if the value could be parsed, Otherwise, returns a meaningful error

fn peek(input: &mut impl Buffer<char>) -> bool

Peek reads the input buffer, returning true if the value could be found, Otherwise, returns false. Not required, but usually provides better performance if implemented

impl<const CHARS: &'static str> PartialEq<OneOf<CHARS>> for OneOf<CHARS>

fn eq(&self, other: &OneOf<CHARS>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &OneOf<CHARS>) -> bool

This method tests for !=.
