[−][src]Function combine::tokens

pub fn tokens<T, I>(tokens: T) -> impl Parser<Input = I, Output = T> where
    T: Clone + IntoIterator,
    I: Stream,
    T::Item: PartialEq<I::Item>,

Parses multiple tokens.

Consumes items from the input and compares them to the values from tokens using the comparison function cmp. Succeeds if all the items from tokens are matched in the input stream and fails otherwise with expected used as part of the error.

let result = tokens("abc".chars())
    .parse("abc")
    .map(|x| x.0.as_str());
assert_eq!(result, Ok("abc"));
