# Objective Since BufferVec was first introduced, `bytemuck` has added additional traits with fewer restrictions than `Pod`. Within BufferVec, we only rely on the constraints of `bytemuck::cast_slice` to a `u8` slice, which now only requires `T: NoUninit` which is a strict superset of `Pod` types. ## Solution Change out the `Pod` generic type constraint with `NoUninit`. Also taking the opportunity to substitute `cast_slice` with `must_cast_slice`, which avoids a runtime panic in place of a compile time failure if `T` cannot be used. --- ## Changelog Changed: `BufferVec` now supports working with types containing `NoUninit` but not `Pod` members. Changed: `BufferVec` will now fail to compile if used with a type that cannot be safely read from. Most notably, this includes ZSTs, which would previously always panic at runtime. |
