Subject: [PATCH v2 0/3] rust: xarray: add `insert` and `reserve`

The reservation API is used by asahi; currently they use their own
abstractions but intend to use these when available.

Rust Binder intends to use the reservation API as well.

Daniel Almeida mentions a use case for `insert_limit`, but didn't name
it specifically.
