Struct bookdata::io::background::ThreadWrite

pub struct ThreadWrite {
    write: Option<PipeWriter>,
    handle: Option<JoinHandle<Result<u64>>>,
}

Writer that writes to a background thread.

Fields

write: Option<PipeWriter>

handle: Option<JoinHandle<Result<u64>>>

Implementations

impl ThreadWrite

pub fn new<W: Write + Send + 'static>(chan: W) -> Result<ThreadWrite>

Push a read into a background thread.

fn do_close(&mut self) -> Result<u64>

pub fn close(self) -> Result<u64>

Close and drop the thread writer.

Trait Implementations

impl Drop for ThreadWrite

fn drop(&mut self)

Executes the destructor for this type.

impl Write for ThreadWrite

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

Flush the thread writer. This is not reliable.

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

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

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

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

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
