Trait Writable 

pub trait Writable {
    type Fmt: Write;
    type IO: Write;

    // Required methods
    fn as_fmt(&mut self) -> Option<&mut Self::Fmt>;
    fn as_io(&mut self) -> Option<&mut Self::IO>;
}

Required Associated Types

type Fmt: Write

type IO: Write

Required Methods

fn as_fmt(&mut self) -> Option<&mut Self::Fmt>

fn as_io(&mut self) -> Option<&mut Self::IO>

This trait is dyn compatible.

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