Struct core::async_iter::FromIter

source · [−]

pub struct FromIter<I> { /* private fields */ }

🔬 This is a nightly-only experimental API. (async_iter_from_iter #81798)

Expand description

An async iterator that was created from iterator.

This async iterator is created by the from_iter function. See it documentation for more.

Trait Implementations

impl<I: Iterator> AsyncIterator for FromIter

source

type Item = ::Item

🔬 This is a nightly-only experimental API. (async_iterator #79024)

The type of items yielded by the async iterator.

fn poll_next(
self: Pin<&mut Self>,
_cx: &mut Context<'_>
) -> Poll<Option<Self::Item>>

source

🔬 This is a nightly-only experimental API. (async_iterator #79024)

Attempt to pull out the next value of this async iterator, registering the current task for wakeup if the value is not yet available, and returning None if the async iterator is exhausted. Read more
