[−][src]Struct tokio::fs::ReadDir
This is supported on crate feature
fs
only.Stream of the entries in a directory.
This stream 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.
Errors
This Stream
will return an Err
if there's some sort of intermittent
IO error during iteration.
Implementations
impl ReadDir
[src]
pub async fn next_entry<'_>(&'_ mut self) -> Result<Option<DirEntry>>
