https://github.com/apache/arrow-rs/blob/3837ac01dcc25ded91bd1e42221f3a9396051841/arrow-integration-testing/src/lib.rs#L190 always returns a "valid" struct (which has [`[repr(C)]`](https://doc.rust-lang.org/nomicon/other-reprs.html#reprc)). This struct is then written to the given `out` pointer here https://github.com/apache/arrow-rs/blob/3837ac01dcc25ded91bd1e42221f3a9396051841/arrow-integration-testing/src/lib.rs#L192. Note that this requires `unsafe` because it's UB if the given pointer is not valid for writes or misaligned (https://doc.rust-lang.org/stable/std/ptr/fn.write.html#safety). -- This is an automated message from the Apache Git Service.
