slimbox

A thin pointer type for heap allocation that stores metadata together with the value, in the same allocation.

slimbox is no_std-compatible (requiring alloc).

The MSRV (Minimum Supported Rust Version) is 1.56, for edition 2021. You can enable the nightly or unsafe_stable features for extra functionality; the nightly feature requires a nightly toolchain (as of 2021-11-17), the unsafe_unstable feature assumes that (potentially-)wide pointers contain a thin pointer at offset 0 - this has been the case for a long time and it shouldn't really change in the future, but it's still an assumption that's not backed by stability guarantees.
