Dandandan opened a new issue #279:
URL: https://github.com/apache/arrow-rs/issues/279
**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
Currently `maybe_usize` and `try_from_trusted_len_iter` are used for the
`take` kernel. It seems we could do better for `u32`, `i32`, and `u64`/ `i64`
(for >64 bit architecture) as we can cast to `usize` directly.
**Describe the solution you'd like**
Specialize on aforementioned types to avoid overhead of the slow path.
**Describe alternatives you've considered**
Implementating/exposing a specialized function for the types.
**Additional context**
