Trait IoBufMut 

pub unsafe trait IoBufMut: IoBuf {
    // Required methods
    fn stable_mut_ptr(&mut self) -> *mut u8;
    unsafe fn set_init(&mut self, pos: usize);
}

A buffer an owned read fills: an IoBuf whose memory past the bytes it holds may be written, and told how many hold data after a read.

Safety

As IoBuf; and stable_mut_ptr points at the same memory, writable for all bytes_total bytes.

Required Methods

fn stable_mut_ptr(&mut self) -> *mut u8

The address of the buffer’s first byte, for writing.

unsafe fn set_init(&mut self, pos: usize)

Sets how many bytes from the start hold data to pos (the runtime calls it with a smaller count too, never below what the caller handed in).

Safety

pos <= bytes_total(), and the first pos bytes are initialized.

Dyn Compatibility

This trait is not dyn compatible.

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