Expand description
Returns a stream of entries in a directory.
The stream yields items of type io::Result
<
DirEntry
>
. Note that I/O errors can
occur while reading from the stream.
This function is an async version of std::fs::read_dir
.
Errors
An error will be returned in the following situations:
path
does not point to an existing directory.- The current process lacks permissions to read the contents of the directory.
- Some other I/O error occurred.
Examples
use async_std::fs;
use async_std::prelude::*;
let mut entries = fs::read_dir(".").await?;
while let Some(res) = entries.next().await {
let entry = res?;
println!("{}", entry.file_name().to_string_lossy());
}
