Struct pooled_writer::PooledWriter

source · [−]

pub struct PooledWriter { /* private fields */ }

Expand description

A PooledWriter is created by exchanging a writer with a Pool.

The pooled writer will internally buffer writes, sending bytes to the Pool after the internal buffer has been filled.

Note that the pool_tx channel is shared by all pooled writers, whereas the writer_tx is specific to the underlying writer that this pooled writer encapsulates.

Implementations

source

impl PooledWriter

source

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

Flush any remaining bytes and consume self, triggering drops of the senders.

Trait Implementations

source

impl Debug for PooledWriter

source

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

Formats the value using the given formatter. Read more

source

impl Drop for PooledWriter

source

fn drop(&mut self)

Drop PooledWriter.

This will flush the writer.

source

impl Write for PooledWriter

source

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

Send all bytes in buf to the Pool.

source

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

Send whatever is in the current buffer even if it is not a full buffer.
