Trait Writable 

pub trait Writable<O: Output> {
    // Required method
    async fn write_to(&self, output: &mut O) -> Result<(), O::Error>;
}

A type that can be written to an output stream.

This struct is typically implemented by generic structs whenever their fields are also Writable. In this way, writable types depend on each other and re-use common syntax.

Required Methods

async fn write_to(&self, output: &mut O) -> Result<(), O::Error>

Writes to the output. Returns the output’s error upon failure.

A writable can always be written multiple times. Because of this, the function takes a borrowed reference.

Dyn Compatibility

This trait is not dyn compatible.

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