Trait BufferMut

pub unsafe trait BufferMut<T>: Buffer<T> {
    // Required methods
    fn as_mut_ptr(&mut self) -> NonNull<T>;
    fn len(&self) -> usize;
    fn capacity(&self) -> usize;
    unsafe fn set_len(&mut self, len: usize) -> bool;
    fn reserve(&mut self, _additional: usize) -> bool;
}

Safety

• as_mut_ptr must point to the start of a memory buffer of capacity, with the first len element initialized.
• slice delimited by as_mut_ptr and len must be the same as Buffer::as_slice

Required Methods

fn as_mut_ptr(&mut self) -> NonNull<T>

fn len(&self) -> usize

fn capacity(&self) -> usize

unsafe fn set_len(&mut self, len: usize) -> bool

Safety

• First len items of buffer slice must be initialized.
• If mem::needs_drop::<T>(), then len must be greater or equal to Self::len.

fn reserve(&mut self, _additional: usize) -> bool
