Required Methods

fn stable_ptr(&self) -> *const u8

Returns a raw pointer to the vector’s buffer.

This method is to be used by the tokio-uring runtime and it is not expected for users to call it directly.

The implementation must ensure that, while the tokio-uring runtime owns the value, the pointer returned by stable_ptr does not change.

fn bytes_init(&self) -> usize

Number of initialized bytes.

This method is to be used by the tokio-uring runtime and it is not expected for users to call it directly.

For Vec, this is identical to len().

fn bytes_total(&self) -> usize

Total size of the buffer, including uninitialized memory, if any.

This method is to be used by the tokio-uring runtime and it is not expected for users to call it directly.

For Vec, this is identical to capacity().
