Trait BufWriter 

pub trait BufWriter {
    type Error;

    // Required methods
    fn encoded_len(&self) -> usize;
    fn write(&self, buf: &mut VacantBuffer<'_>) -> Result<usize, Self::Error>;
}

Writing self to the VacantBuffer in bytes format.

Required Associated Types

type Error

The error type.

Required Methods

fn encoded_len(&self) -> usize

The length of the encoded bytes.

fn write(&self, buf: &mut VacantBuffer<'_>) -> Result<usize, Self::Error>

Encode self to bytes and write to the VacantBuffer.

Returns the number of bytes written if successful.
