Trait Writer 

pub trait Writer {
    // Required method
    fn write(&mut self, bytes: &[u8]);

    // Provided methods
    fn write_byte(&mut self, byte: u8) { ... }
    fn reserve(&mut self, _additional: usize) { ... }
    fn write_with(&mut self, len: usize, fill: impl FnOnce(&mut [u8]) -> usize) { ... }
}

Byte sink used by every serializer in this crate.

Vec<u8> is the primary implementation; IoWriter adapts any std::io::Write with an internal buffer.

Required Methods

fn write(&mut self, bytes: &[u8])

Provided Methods

fn write_byte(&mut self, byte: u8)

fn reserve(&mut self, _additional: usize)

fn write_with(&mut self, len: usize, fill: impl FnOnce(&mut [u8]) -> usize)

Hands the sink a scratch region of len bytes, keeps the first fill(region) bytes of it and discards the rest.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
