Struct object::write::StreamingBuffer

source ·
pub struct StreamingBuffer<W> { /* private fields */ }
Expand description

A WritableBuffer that streams data to a Write implementation.

Self::result must be called to determine if an I/O error occurred during writing.

It is advisable to use a buffered writer like BufWriter instead of an unbuffered writer like File.

Implementations§

source§

impl<W> StreamingBuffer<W>

source

pub fn new(writer: W) -> Self

source

pub fn into_inner(self) -> W

Unwraps this StreamingBuffer giving back the original writer.

source

pub fn result(&mut self) -> Result<(), Error>

Returns any error that occurred during writing.
