> `Float16 -> Float32` and `Float32 -> Float16` use the generic numeric cast. The safe path calls `unary_opt(num_cast)`, so every element builds an `Option` and the validity bitmap is rebuilt. These two conversions cannot fail: every `f16` widens exactly, and every `f32` rounds to an `f16`. is this still applicable after https://github.com/apache/arrow-rs/pull/11219 has been merged? -- This is an automated message from the Apache Git Service.
