Struct `LineWriter`

struct LineWriter<W: AsyncWrite> { ... }

Wrap a writer, like BufWriter does, but prioritizes buffering lines

This was written based on std::io::LineWriter which goes into further details explaining the code.

Buffering is actually done using BufWriter. This class will leverage BufWriter to write on-each-line.

Implementations

fn new(inner: W) -> Self: Create a new LineWriter with default buffer capacity. The default is currently 1KB which was taken from std::io::LineWriter
fn with_capacity(capacity: usize, inner: W) -> Self: Creates a new LineWriter with the specified buffer capacity.
fn buffer(self: &Self) -> &[u8]: Returns a reference to buf_writer's internally buffered data.
fn get_ref(self: &Self) -> &W: Acquires a reference to the underlying sink or stream that this combinator is pulling from.

fn into(self: Self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of [From]<T> for U chooses to do.

fn poll_write(self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &[u8]) -> Poll<Result<usize>>
fn poll_write_vectored(self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>]) -> Poll<Result<usize>>
fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>: Forward to buf_writer 's BufWriter::poll_flush()
fn poll_close(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>: Forward to buf_writer 's BufWriter::poll_close()
