Piggybacking on the [motivation in winit]: `lazy_static!` is a macro whereas `once_cell` achieves the same using generics. Its implementation has also been [proposed for inclusion in `std`], making it easier to switch to a standardized version if/when that happens. The author of that winit PR is making this change to many more crates, slowly turning the scales in favour of `once_cell` in most dependency trees. Furthermore `lazy_static` hasn't published any updates for 3 years. See also [the `once_cell` F.A.Q.]. In addition "constant" `Vec`tor allocations don't need to be wrapped in a `lazy_static!` macro call at all but can be replaced with true `const` slices (or `const` sized arrays, but those are slightly more tedious to construct).

There was a problem hiding this comment.
nice! this could have been done independently anyway. No reason for these being Vecs
Yeah, not sure when it lands but this brings us a step closer at least :) |
