Trait BufMut 

pub trait BufMut {
    // Required methods
    fn len(&self) -> usize;
    fn append_slice(&mut self, val: &[u8]);
    fn set_slice(&mut self, pos: usize, val: &[u8]);

    // Provided methods
    fn is_empty(&self) -> bool { ... }
    fn encode_atom<F>(&mut self, kind: impl Into<FourCC>, f: F) -> Result<()>
       where Self: Sized,
             F: FnOnce(&mut Self) -> Result<()> { ... }
}

A mutable contiguous buffer of bytes.

Required Methods

fn len(&self) -> usize

fn append_slice(&mut self, val: &[u8])

fn set_slice(&mut self, pos: usize, val: &[u8])

Provided Methods

fn is_empty(&self) -> bool

fn encode_atom<F>(&mut self, kind: impl Into<FourCC>, f: F) -> Result<()>

where Self: Sized, F: FnOnce(&mut Self) -> Result<()>,

Write a box header (size(4) + kind(4)) with a placeholder size, run f to encode the body, then go back and patch the placeholder with the total number of bytes written (header included).

Dyn Compatibility

This trait is dyn compatible.

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