Struct allsorts::binary::write::WriteBuffer

pub struct WriteBuffer { /* private fields */ }

An in-memory buffer that implements WriteContext.

Implementations

impl WriteBuffer

pub fn new() -> Self

Create a new, empty WriteBuffer

pub fn bytes(&self) -> &[u8]

Retrieve a slice of the data held by this buffer

pub fn clear(&mut self)

Clear the internal data so that this buffer can be reused

pub fn len(&self) -> usize

Returns the current size of the data held by this buffer

pub fn into_inner(self) -> Vec<u8>

Consume self and return the inner buffer

Trait Implementations

impl WriteContext for WriteBuffer

fn write_bytes(&mut self, data: &[u8]) -> Result<(), WriteError>

Write a slice of bytes to a WriteContext.

fn write_zeros(&mut self, count: usize) -> Result<(), WriteError>

Write the specified number of zero bytes to the WriteContext.

fn bytes_written(&self) -> usize

The total number of bytes written so far.

fn write_placeholder<T, HostType>( &mut self, placeholder: Placeholder<T, HostType>, val: HostType, ) -> Result<T::Output, WriteError>

where T: WriteBinary<HostType>,

Consumes the placeholder and writes the supplied value into it

fn write_placeholder_dep<T, HostType>( &mut self, placeholder: Placeholder<T, HostType>, val: HostType, args: T::Args, ) -> Result<T::Output, WriteError>

where T: WriteBinaryDep<HostType>,

Consumes the placeholder and writes the supplied value into it. WriteBinaryDep version

fn write_array<'a, T>( &mut self, array: &ReadArray<'a, T>, ) -> Result<(), WriteError>

where Self: Sized, T: ReadUnchecked + WriteBinary<<T as ReadUnchecked>::HostType>,

Write a ReadArray instance to a WriteContext.

fn write_vec<T, HostType>( &mut self, vec: Vec<HostType>, ) -> Result<(), WriteError>

where Self: Sized, T: WriteBinary<HostType>,

Write a Vec into a WriteContext.

fn write_iter<T, HostType>( &mut self, iter: impl Iterator<Item = HostType>, ) -> Result<(), WriteError>

where Self: Sized, T: WriteBinary<HostType>,

Write a slice of values into a WriteContext.

fn placeholder<'a, T, HostType>( &mut self, ) -> Result<Placeholder<T, HostType>, WriteError>

where T: WriteBinary<HostType> + ReadUnchecked,

Return a placeholder to T in the context for filling in later.

fn reserve<'a, T, HostType>( &mut self, count: usize, ) -> Result<Placeholder<T, &'a HostType>, WriteError>

where T: WriteBinaryDep<&'a HostType>,

Reserve space for count bytes in the context for filling in later.

fn placeholder_array<'a, T, HostType>( &mut self, count: usize, ) -> Result<Vec<Placeholder<T, HostType>>, WriteError>

where T: WriteBinary<HostType> + ReadUnchecked,

Return a Vec of count placeholders of type T.
