Andy Grove updated ARROW-10973:
-------------------------------
Fix Version/s: (was: 3.0.0)
> [Rust] Document use of unsafe in compute kernels
> ------------------------------------------------
>
> Key: ARROW-10973
> URL: https://issues.apache.org/jira/browse/ARROW-10973
> Project: Apache Arrow
> Issue Type: Sub-task
> Components: Rust
> Reporter: Andy Grove
> Priority: Major
>
> There are ~7 uses of unsafe in the compute kernels and we should document
> them according to the guidelines in the Arrow crate README
>
> {code:java}
> // JUSTIFICATION
> // Benefit
> // Describe the benefit of using unsafe. E.g.
> // "30% performance degradation if the safe counterpart is used, see
> bench X."
> // Soundness
> // Describe why the code remains sound (according to the definition of
> rust's unsafe code guidelines). E.g.
> // "We bounded check these values at initialization and the array is
> immutable."
> let ... = unsafe { ... }; {code}
