Struct glommio::io::Directory

pub struct Directory { /* fields omitted */ }

A directory representation where asynchronous operations can be issued

Implementations

impl Directory

pub fn try_clone(&self) -> Result<Directory, ()>

Try creating a clone of this Directory.

The new object has a different file descriptor and has to be closed separately.

pub async fn open<P: AsRef<Path>>(path: P) -> Result<Directory, ()>

Asynchronously open the directory at path

pub async fn open_file<P: AsRef<Path>>(&self, path: P) -> Result<DmaFile, ()>

Opens a file under this directory, returns a DMA file

NOTE: Path must not contain directories and just be a file name

pub async fn create<P: AsRef<Path>>(path: P) -> Result<Directory, ()>

Similar to create() in the standard library, but returns a DMA file

pub async fn create_file<P: AsRef<Path>>(&self, path: P) -> Result<DmaFile, ()>

Creates a file under this directory, returns a DMA file

NOTE: Path must not contain directories and just be a file name

pub fn sync_read_dir(&self) -> Result<ReadDir, ()>

Returns an iterator to the contents of this directory

pub async fn sync(&self) -> Result<(), ()>

Issues fdatasync into the underlying file.

pub async fn close(self) -> Result<(), ()>

Closes this DMA file.

pub fn path(&self) -> Option<Ref<'_, Path>>

Returns an Option containing the path associated with this open directory, or None if there isn’t one.
