Struct mentat_parser_utils::value_and_span::Stream

pub struct Stream<'a>(_, _);

A single combine::Stream implementation iterating edn::ValueAndSpan instances. Equivalent to combine::IteratorStream as produced by combine::from_iter, but specialized to edn::ValueAndSpan.

Trait Implementations

impl<'a> Clone for Stream<'a>

fn clone(&self) -> Stream<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Streaming<'a> for Stream<'a>

fn as_stream(self) -> Stream<'a>

impl<'a> StreamOnce for Stream<'a>

Equivalent to combine::IteratorStream.

type Item = &'a ValueAndSpan

The type of items which is yielded from this stream.

type Range = &'a ValueAndSpan

The type of a range of items yielded from this stream. Types which do not a have a way of yielding ranges of items should just use the Self::Item for this type.

type Position = SpanPosition

Type which represents the position in a stream. Ord is required to allow parsers to determine which of two positions are further ahead.

fn uncons(&mut self) -> Result<Self::Item, Error<Self::Item, Self::Item>>

Takes a stream and removes its first item, yielding the item and the rest of the elements. Returns Err if no element could be retrieved.

fn position(&self) -> Self::Position

Returns the current position of the stream.
