-# OptiPNG
-
-- Source: <https://sourceforge.net/project/optipng>
-- Version: v0.7.7
-
-## Dependencies
-
-- Docker
-
-## Example
-
-See `example.html`
-
-## API
-
-### `int version()`
-
-Returns the version of optipng as a number. va.b.c is encoded as 0x0a0b0c
-
-### `ArrayBuffer compress(std::string buffer, {level})`;
-
-`compress` will re-compress the given PNG image via `buffer`. `level` is a number between 0 and 7.
-
-### `void free_result()`
-
-Frees the result created by `compress()`.

+//! 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
