Trait WriteExt

    // Provided methods
    fn emit_u8(&mut self, v: u8) -> Result<(), Error> { ... }
    fn emit_u16(&mut self, v: u16) -> Result<(), Error> { ... }

    ) -> Result<usize, Error> { ... }
}

Utility trait to write some primitive values into our encoding format.

Provided Methods

fn emit_u8(&mut self, v: u8) -> Result<(), Error>

Write an 8-bit unsigned integer in little-endian.

fn emit_u16(&mut self, v: u16) -> Result<(), Error>

Write a 16-bit unsigned integer in little-endian.

fn emit_u32(&mut self, v: u32) -> Result<(), Error>

Write a 32-bit unsigned integer in little-endian.

fn emit_u64(&mut self, v: u64) -> Result<(), Error>

Write a 64-bit unsigned integer in little-endian.

fn emit_slice(&mut self, slice: &[u8]) -> Result<(), Error>

Write the entire slice to the writer.

fn emit_compact_size(&mut self, value: impl Into<u64>) -> Result<usize, Error>

Write a value in compact size aka “VarInt” encoding.

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.
