Struct tracing::stdlib::async_iter::FromIter

pub struct FromIter<I> {
    iter: I,
}

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

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> AsyncIterator for FromIter<I>

where I: Iterator,

type Item = <I as Iterator>::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 FromIter<I>>, _cx: &mut Context<'_>, ) -> Poll<Option<<FromIter<I> as AsyncIterator>::Item>>

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

Attempts 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.

fn size_hint(&self) -> (usize, Option<usize>)

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

Returns the bounds on the remaining length of the async iterator.

impl<I> Clone for FromIter<I>

where I: Clone,

fn clone(&self) -> FromIter<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> Debug for FromIter<I>

where I: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
