Add `[Option<T>; N]::transpose` This PR as a new unstable libs API, `[Option<T>; N]::transpose`, which permits going from `[Option<T>; N]` to `Option<[T; N]>`. This new API doesn't have an ACP as it was directly asked by T-libs-api in https://github.com/rust-lang/rust/issues/97601#issuecomment-2372109119: > [..] but it'd be trivial to provide a helper method `.transpose()` that turns array-of-Option into Option-of-array (**and we think that method should exist**; it already does for array-of-MaybeUninit). r? libs |
