Trait IoBufMut 

pub unsafe trait IoBufMut: Send + 'static {
    // Required methods
    fn as_mut_ptr(&mut self) -> *mut u8;
    fn capacity(&self) -> usize;
}

A buffer that can be used for io_uring read operations.

Safety

Implementors must guarantee that:

• The pointer returned by as_mut_ptr() remains valid and at a stable address until the I/O operation completes, even if self is moved.
• This is automatically satisfied for heap-allocated buffers (Vec<u8>, Box<[u8]>, etc.) but NOT for stack-allocated arrays.

Required Methods

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

Returns a mutable pointer to the buffer’s data.

fn capacity(&self) -> usize

Returns the buffer’s total capacity (maximum bytes that can be read into it).
