Expand description

Trait that allows appending bytes. Used especially by the NestedEncode trait to output data.

In principle it can be anything, but in practice we only keep 1 implementation, which is Vec. This is to avoid code duplication by monomorphization.

Required Methods§

Source

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

Write to the output.

Provided Methods§

Source

fn push_byte(&mut self, byte: u8)

Write a single byte to the output.

Source

fn supports_specialized_type<T: TryStaticCast>() -> bool

Source

fn push_specialized<T, C, H>( &mut self, _context: C, _value: &T, h: H, ) -> Result<(), H::HandledErr>
where T: TryStaticCast, C: TryStaticCast, H: EncodeErrorHandler,

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
