Required Methods§

Source

fn shape(&self) -> &[usize]

Get the shape of this tensor map.

Source

fn unmap(&mut self)

Unmap the tensor from memory.

Source

fn as_slice(&self) -> &[T]

Get a slice to the data in this tensor map.

Source

fn as_mut_slice(&mut self) -> &mut [T]

Get a mutable slice to the data in this tensor map.

Source

fn is_writable(&self) -> bool

Whether this mapping permits writes – i.e. whether the coherency bracket it holds will flush on release.

The single source of truth for a binding that has to advertise mutability to a foreign consumer (the Python buffer protocol’s readonly flag, say). Deriving that from the access a caller requested instead would leave the advertisement agreeing with the request while both disagreed with the mapping actually taken.
