Struct zng_task::fs::ReadDir

pub struct ReadDir(/* private fields */);

Expand description

A stream of entries in a directory.

This stream is returned by read_dir() and yields items of type io::Result<DirEntry>. Each DirEntry can then retrieve information like entry’s path or metadata.

Trait Implementations§

§

impl Debug for ReadDir

§

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

Formats the value using the given formatter. Read more

§

impl Stream for ReadDir

§

type Item = Result<DirEntry, Error>

Values yielded by the stream.

§

fn poll_next( self: Pin<&mut ReadDir>, cx: &mut Context<'_>, ) -> Poll<Option<<ReadDir as Stream>::Item>>

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

§

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

Returns the bounds on the remaining length of the stream. Read more
