Struct Empty 

pub struct Empty;

Empty ignores any data written via Write, and will always be empty (returning zero bytes) when read via Read.

This struct is generally created by calling empty. Please see the documentation of empty for more details.

Trait Implementations

impl Clone for Empty

fn clone(&self) -> Empty

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Empty

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

Formats the value using the given formatter.

impl Default for Empty

fn default() -> Empty

Returns the “default value” for a type.

impl Read for Empty

async fn read(&mut self, _buf: &mut [u8]) -> Result<usize>

Reads data from the stream into the provided buffer.

fn read_vectored( &mut self, bufs: &mut [IoSliceMut<'_>], ) -> impl Future<Output = Result<usize>>

fn is_read_vectored(&self) -> bool

fn read_to_end( &mut self, buf: &mut Vec<u8>, ) -> impl Future<Output = Result<usize>>

fn read_to_string(&mut self) -> impl Future<Output = Result<String>>

fn read_exact(&mut self, buf: &mut [u8]) -> impl Future<Output = Result<()>>

impl Seek for Empty

async fn seek(&mut self, _pos: SeekFrom) -> Result<u64>

Moves the cursor to a new position within the stream.

fn rewind(&mut self) -> impl Future<Output = Result<u64>>

Rewind to the beginning of a stream.

fn stream_position(&mut self) -> impl Future<Output = Result<u64>>

Returns the current seek position from the start of the stream.

fn seek_relative(&mut self, offset: i64) -> impl Future<Output = Result<u64>>

Seeks relative to the current position.

impl Write for Empty

async fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were successfully written.

async fn flush(&mut self) -> Result<()>

Flushes the output streamer, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored( &mut self, bufs: &[IoSlice<'_>], ) -> impl Future<Output = Result<usize>>

Like write, except that it writes from a slice of buffers.

fn write_all(&mut self, buf: &[u8]) -> impl Future<Output = Result<()>>

Attempts to write an entire buffer into this writer.

impl Copy for Empty
