Trait SerWrite 

pub trait SerWrite {
    type Error;

    // Required method
    fn write(&mut self, buf: &[u8]) -> Result<(), Self::Error>;

    // Provided methods
    fn write_byte(&mut self, byte: u8) -> Result<(), Self::Error> { ... }
    fn write_str(&mut self, s: &str) -> Result<(), Self::Error> { ... }
}

Serializers should write data to the implementations of this trait.

Required Associated Types

type Error

An error type returned from the trait methods.

Required Methods

fn write(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write all bytes from buf to the internal buffer.

Otherwise return an error.

Provided Methods

fn write_byte(&mut self, byte: u8) -> Result<(), Self::Error>

Write a single byte to the internal buffer.

Return an error if the operation could not succeed.

fn write_str(&mut self, s: &str) -> Result<(), Self::Error>

Write a whole string to the internal buffer.

Otherwise return an error.

Dyn Compatibility

This trait is dyn compatible.

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