-//! This is a module that provides `malloc` and `free` for `libdeflate`.
-//! These implementations are compatible with the standard signatures
-//! but use Rust allocator instead of including libc one as well.
-//!
-//! Rust allocator APIs requires passing size and alignment to the
-//! `dealloc` function. This is different from C API, which only
-//! expects a pointer in `free` and expects allocators to take care of
-//! storing any necessary information elsewhere.
-//!
-//! In order to simulate C API, we allocate a `size_and_data_ptr`
-//! of size `sizeof(usize) + size` where `size` is the requested number
-//! of bytes. Then, we store `size` at the beginning of the allocated
-//! chunk (within those `sizeof(usize)` bytes) and return
-//! `data_ptr = size_and_data_ptr + sizeof(usize)` to the calleer:
-//!
-//! [`size`][...actual data]
-//! -^------------------ `size_and_data_ptr`
-//! ---------^---------- `data_ptr`
-//!
-//! Then, in `free`, the caller gives us `data_ptr`. We can subtract
-//! `sizeof(usize)` back and get the original `size_and_data_ptr`.
-//! At this point we can read `size` back and call the Rust `dealloc`
-//! for the whole allocated chunk.
-//!
-//! I've raised an upstream issue to hopefully make this easier in
-//! future: https://github.com/ebiggers/libdeflate/issues/62
