Struct futures::io::LineWriter

pub struct LineWriter<W>where
    W: AsyncWrite,
{ /* private fields */ }
Expand description

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§

Create a new LineWriter with default buffer capacity. The default is currently 1KB which was taken from std::io::LineWriter

Creates a new LineWriter with the specified buffer capacity.

Returns a reference to buf_writer’s internally buffered data.

Acquires a reference to the underlying sink or stream that this combinator is pulling from.
