[AnubhabB]

Primarily 2 sources of warnings/ errors:

Clippy complains about Needless Lifetimes:

#[warn(clippy::needless_lifetimes)]

185 | impl<'a> Load for st::TensorView<'a> {
    |      ^^                          ^^
    |
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#needless_lifetimes
    = note: `#[warn(clippy::needless_lifetimes)]` on by default
help: elide the lifetimes
    |
185 - impl<'a> Load for st::TensorView<'a> {
185 + impl Load for st::TensorView<'_> {

Manual Ceil Div

#[warn(clippy::manual_div_ceil)]

    |                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: consider using `.div_ceil()`: `position.div_ceil(alignment)`

All test cases seem to pass for cuda, metal and cpu across multiple runs.
