Struct BufferWriter

pub struct BufferWriter<'a> { /* private fields */ }

Writer backend for a byte slice

Implementations

impl<'a> BufferWriter<'a>

pub fn new(buffer: &'a mut [u8]) -> BufferWriter<'a>

Create a new BufferWriter

pub fn cursor(&self) -> usize

How many bytes have been written thus far

Trait Implementations

impl<'a> StreamingWriter for BufferWriter<'a>

type Error = BufferWriterError

The kind of errors that the implementation emits during encoding

fn write_bytes(&mut self, bytes: &[u8]) -> Result<(), Self::Error>

Write all of the bytes from the provided buffer into the underlying encoding stream.

fn share_bytes_mut( &mut self, len: usize, ) -> Result<&mut [MaybeUninit<u8>], Self::Error>

Expose an aliased view of a subset of the underlying data as mutable bytes.

fn flush() -> Result<(), Self::Error>

Ensure that all bytes are fully written in a maximally durable fashion.
