Trait Stream

pub trait Stream: Clone {
    type Item: Positioner;

    // Required method
    fn uncons(self) -> Result<(Self::Item, Self), Error<Self::Item>>;
}

A stream is a sequence of items that can be extracted one by one

Required Associated Types

type Item: Positioner

Required Methods

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

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

impl<'a> Stream for &'a str

type Item = char

fn uncons(self) -> Result<(char, &'a str), Error<char>>

impl<'a, T> Stream for &'a [T]

where T: Positioner,

type Item = &'a T

fn uncons(self) -> Result<(&'a T, &'a [T]), Error<&'a T>>
