Trait IoBuf 

pub trait IoBuf: 'static {
    // Required method
    fn as_init(&self) -> &[u8] ;
}

A trait for immutable buffers.

The IoBuf trait is implemented by buffer types that can be passed to immutable completion-based IO operations, like writing its content to a file. This trait will only take initialized bytes of a buffer into account.

Required Methods

fn as_init(&self) -> &[u8]

Get the slice of initialized bytes.

Dyn Compatibility

This trait is dyn compatible.

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