Struct object::write::StreamingBuffer

pub struct StreamingBuffer<W> { /* private fields */ }

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

impl<W> StreamingBuffer<W>

pub fn new(writer: W) -> Self

Create a new StreamingBuffer backed by the given writer.

pub fn into_inner(self) -> W

Unwraps this StreamingBuffer giving back the original writer.

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

Returns any error that occurred during writing.

Trait Implementations

impl<W: Debug> Debug for StreamingBuffer<W>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<W: Write> WritableBuffer for StreamingBuffer<W>

fn len(&self) -> usize

Returns position/offset for data to be written at.

fn reserve(&mut self, _size: usize) -> Result<(), ()>

Reserves specified number of bytes in the buffer.

fn resize(&mut self, new_len: usize)

Writes zero bytes at the end of the buffer until the buffer has the specified length.

fn write_bytes(&mut self, val: &[u8])

Writes the specified slice of bytes at the end of the buffer.

fn write_pod<T: Pod>(&mut self, val: &T)where
    Self: Sized,

Writes the specified Pod type at the end of the buffer.

fn write_pod_slice<T: Pod>(&mut self, val: &[T])where
    Self: Sized,

Writes the specified Pod slice at the end of the buffer.
