Required methods

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

Write a slice of bytes to a WriteContext.

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

Write the specified number of zero bytes to the WriteContext.

fn bytes_written(&self) -> usize[src]

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>, [src]

Consumes the placeholder and writes the supplied value into it
