Trait Implementations

impl Debug for PipeSide

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

Formats the value using the given formatter.

impl Device for PipeSide

fn name(&self) -> &str

fn read(&self, _offset: u64, buf: &mut [u8]) -> Result<u64, FileSystemError>

fn write(&self, _offset: u64, buf: &[u8]) -> Result<u64, FileSystemError>

fn close(&self) -> Result<(), FileSystemError>

Informs the device that it is closed.

fn clone_device(&self) -> Result<(), FileSystemError>

Informs the device that it is cloned.

fn set_size(&self, _size: u64) -> Result<(), FileSystemError>

fn try_create(&self) -> Option<Result<Arc<dyn Device>, FileSystemError>>

Open the device. This tells the device manager that when opening a file with this device name, it should instead use the device returned by this function. if None, it will just use the device directly.
