Struct ReadDir
struct ReadDir(_)
Reads the entries in a directory.
This struct is returned from the read_dir function of this module and
will yield instances of DirEntry. Through a DirEntry information
like the entry's path and possibly other metadata can be learned.
A ReadDir can be turned into a Stream with ReadDirStream.
Errors
This stream will return an Err if there's some sort of intermittent
IO error during iteration.
Implementations
impl ReadDir
async fn next_entry(self: &mut Self) -> Result<Option<DirEntry>>Returns the next entry in the directory stream.
Cancel safety
This method is cancellation safe.
fn poll_next_entry(self: &mut Self, cx: &mut Context<'_>) -> Poll<Result<Option<DirEntry>>>Polls for the next directory entry in the stream.
This method returns:
Poll::Pendingif the next directory entry is not yet available.Poll::Ready(Ok(Some(entry)))if the next directory entry is available.Poll::Ready(Ok(None))if there are no more directory entries in this stream.Poll::Ready(Err(err))if an IO error occurred while reading the next directory entry.
When the method returns
Poll::Pending, theWakerin the providedContextis scheduled to receive a wakeup when the next directory entry becomes available on the underlying IO resource.Note that on multiple calls to
poll_next_entry, only theWakerfrom theContextpassed to the most recent call is scheduled to receive a wakeup.
