Struct chumsky::stream::Stream

pub struct Stream<'a, I, S: Span, Iter: Iterator<Item = (I, S)> + ?Sized = dyn StreamExtend<(I, S)> + 'a> { /* fields omitted */ }

A type that represents a stream of input tokens. Unlike Iterator, this type supports backtracking and a few other features required by the crate.

Implementations

impl<'a, I, S: Span, Iter: Iterator<Item = (I, S)>> Stream<'a, I, S, Iter>

pub fn from_iter(eoi: S, iter: Iter) -> Self

Create a new stream from an iterator of (Token, Span) tuples. A span representing the end of input must also be provided.

There is no requirement that spans must map exactly to the position of inputs in the stream, but they should be non-overlapping and should appear in a monotonically-increasing order.

Trait Implementations

impl<'a, T: Clone> From<&'a [T]> for Stream<'a, T, Range<usize>, Box<dyn Iterator<Item = (T, Range<usize>)> + 'a>>

fn from(s: &'a [T]) -> Self

Performs the conversion.
