Hi!
I’ve noticed this piece of code in your library:
#[inline]
fn as_mut_slice(&self) -> &mut [u8] {
unsafe {
match self {
&OwnedBuffer(ref v) => {
let mut_v: &mut Vec<u8> = mem::transmute(v);
mut_v.as_mut_slice()
},
&BorrowedBuffer(ref s) => {
let mut_s: &mut &mut [u8] = mem::transmute(s);
mut_s.as_mut_slice()
},
}
}
}
I was under impression that transmuting & to &mut is undefined behavior in
Rust, and you need to use RefCell (or UnsafeCell) for this. Am I wrong?
