Struct IoWriter 

pub struct IoWriter<W: Write> { /* private fields */ }

Buffered adapter that lets any std::io::Write act as a Writer.

Errors are sticky: the first failure stops all further output and is returned by IoWriter::finish. Buffered bytes are only written by IoWriter::finish or IoWriter::into_result; dropping the adapter discards them.

Implementations

impl<W: Write> IoWriter<W>

pub fn new(inner: W) -> Self

pub fn with_capacity(capacity: usize, inner: W) -> Self

pub fn finish(self) -> Result<W>

Flushes the buffer and returns the wrapped writer, or the first error that occurred.

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

Trait Implementations

impl<W: Write> Writer for IoWriter<W>

fn write(&mut self, bytes: &[u8])

fn write_byte(&mut self, byte: u8)

fn write_with(&mut self, len: usize, fill: impl FnOnce(&mut [u8]) -> usize)

Hands the sink a scratch region of len bytes, keeps the first fill(region) bytes of it and discards the rest.

fn reserve(&mut self, _additional: usize)
