This repository contains a few interconnected Rust libraries that enable generic, dynamic data structures in environments that do not have a global allocator or where its usage should be avoided.

• alloc-traits: This base crate contains a trait which defines the contract of a local allocator, substituting or supplementing the global allocator.
• static-alloc: Defines a limited allocator that requires no runtime operating system interaction by allocating from a memory region embedded in the program binary, and allocated by the program loader.
• unsize: A utility trait that can replace the unstable internal trait combination Unsize/CoerceUnsize so that custom smart pointers such as boxes can be unsized.
• without-alloc: Defines data structures similar to those in alloc which do not require a global allocator. They instead work on a once-allocated memory region with interoperability with allocators that impl alloc-traits traits.
