-mod range;
-+//! ThinVec is exactly the same as Vec, except that it stores its `len` and `capacity` in the buffer
-+//! it allocates.
-+//!
-+//! This makes the memory footprint of ThinVecs lower; notably in cases where space is reserved for
-+//! a non-existence ThinVec<T>. So `Vec<ThinVec<T>>` and `Option<ThinVec<T>>::None` will waste less
-+//! space. Being pointer-sized also means it can be passed/stored in registers.
-+//!
-+//! Of course, any actually constructed ThinVec will theoretically have a bigger allocation, but
-+//! the fuzzy nature of allocators means that might not actually be the case.
-+//!
-+//! Properties of Vec that are preserved:
-+//! * `ThinVec::new()` doesn't allocate (it points to a statically allocated singleton)
-+//! * reallocation can be done in place
-+//! * `size_of::<ThinVec<T>>()` == `size_of::<Option<ThinVec<T>>>()`
-+//!
-+//! Properties of Vec that aren't preserved:
-+//! * `ThinVec<T>` can't ever be zero-cost roundtripped to a `Box<[T]>`, `String`, or `*mut T`
-+//! * `from_raw_parts` doesn't exist
-+//! * ThinVec currently doesn't bother to not-allocate for Zero Sized Types (e.g. `ThinVec<()>`),
-+//!   but it could be done if someone cared enough to implement it.

-+//!
-+//! # Gecko FFI
-+//!
-+//! If you enable the gecko-ffi feature, ThinVec will verbatim bridge with the nsTArray type in
-+//! Gecko (Firefox). That is, ThinVec and nsTArray have identical layouts *but not ABIs*, 
-+//! so nsTArrays/ThinVecs an be natively manipulated by C++ and Rust, and ownership can be 
-+//! transferred across the FFI boundary (**IF YOU ARE CAREFUL, SEE BELOW!!**).
-+//!
-+//! While this feature is handy, it is also inherently dangerous to use because Rust and C++ do not
-+//! know about eachother. Specifically, this can be an issue with non-POD types (types which
-+//! have destructors, move constructors, or are `!Copy`).
-+//!
-+//! ## Do Not Pass By Value
-+//!
-+//! The biggest thing to keep in mind is that **FFI functions cannot pass ThinVec/nsTArray 
-+//! by-value**. That is, these are busted APIs:
-+//!
-+//! ```rust,ignore
-+//! // BAD WRONG
-+//! extern fn process_data(data: ThinVec<u32>) { ... }
-+//! // BAD WRONG
-+//! extern fn get_data() -> ThinVec<u32> { ... }
-+//! ```
-+//!
-+//! You must instead pass by-reference:
-+//!
-+//! ```rust
-+//! # use thin_vec::*;
-+//! # use std::mem;
-+//!
-+//! // Read-only access, ok!
-+//! extern fn process_data(data: &ThinVec<u32>) {
-+//!     for val in data {
-+//!         println!("{}", val);
-+//!     }
-+//! }
-+//! 
-+//! // Replace with empty instance to take ownership, ok!
-+//! extern fn consume_data(data: &mut ThinVec<u32>) {
-+//!     let owned = mem::replace(data, ThinVec::new());
-+//!     mem::drop(owned);
-+//! }
-+//! 
-+//! // Mutate input, ok!
-+//! extern fn add_data(dataset: &mut ThinVec<u32>) {
-+//!     dataset.push(37);
-+//!     dataset.push(12);
-+//! }
-+//! 
-+//! // Return via out-param, usually ok!
-+//! //
-+//! // WARNING: output must be initialized! (Empty nsTArrays are free, so just do it!)
-+//! extern fn get_data(output: &mut ThinVec<u32>) {
-+//!     *output = thin_vec![1, 2, 3, 4, 5];
-+//! }
-+//! ```
-+//!
-+//! Ignorable Explanation For Those Who Really Want To Know Why:
-+//!
-+//! > The fundamental issue is that Rust and C++ can't currently communicate about destructors, and
-+//! > the semantics of C++ require destructors of function arguments to be run when the function
-+//! > returns. Whether the callee or caller is responsible for this is also platform-specific, so
-+//! > trying to hack around it manually would be messy. 
-+//! >
-+//! > Also a type having a destructor changes its C++ ABI, because that type must actually exist 
-+//! > in memory (unlike a trivial struct, which is often passed in registers). We don't currently
-+//! > have a way to communicate to Rust that this is happening, so even if we worked out the
-+//! > destructor issue with say, MaybeUninit, it would still be a non-starter without some RFCs
-+//! > to add explicit rustc support.
-+//! >
-+//! > Realistically, the best answer here is to have a "heavier" bindgen that can secretly
-+//! > generate FFI glue so we can pass things "by value" and have it generate by-reference code
-+//! > behind our back (like the cxx crate does). This would muddy up debugging/searchfox though.
-+//!
-+//! ## Types Should Be Trivially Relocatable
-+//!
-+//! Types in Rust are always trivially relocatable (unless suitably borrowed/[pinned][]/hidden).
-+//! This means all Rust types are legal to relocate with a bitwise copy, you cannot provide
-+//! copy or move constructors to execute when this happens, and the old location won't have its
-+//! destructor run. This will cause problems for types which have a significant location
-+//! (types that intrusively point into themselves or have their location registered with a service).
-+//!
-+//! While relocations are generally predictable if you're very careful, **you should avoid using
-+//! types with significant locations with Rust FFI**.
-+//!
-+//! Specifically, ThinVec will trivially relocate its contents whenever it needs to reallocate its
-+//! buffer to change its capacity. This is the default reallocation strategy for nsTArray, and is
-+//! suitable for the vast majority of types. Just be aware of this limitation!
-+//!
-+//! ## Auto Arrays Are Dangerous
-+//!
-+//! ThinVec has *some* support for handling auto arrays which store their buffer on the stack, 
-+//! but this isn't well tested.
-+//!
-+//! Regardless of how much support we provide, Rust won't be aware of the buffer's limited lifetime,
-+//! so standard auto array safety caveats apply about returning/storing them! ThinVec won't ever
-+//! produce an auto array on its own, so this is only an issue for transferring an nsTArray into
-+//! Rust.
-+//!
-+//! ## Other Issues
-+//!
-+//! Standard FFI caveats also apply: 
-+//!
-+//!  * Rust is more strict about POD types being initialized (use MaybeUninit if you must)
-+//!  * `ThinVec<T>` has no idea if the C++ version of `T` has move/copy/assign/delete overloads
-+//!  * `nsTArray<T>` has no idea if the Rust version of `T` has a Drop/Clone impl
-+//!  * C++ can do all sorts of unsound things that Rust can't catch
-+//!  * C++ and Rust don't agree on how zero-sized/empty types should be handled
-+//!
-+//! The gecko-ffi feature will not work if you aren't linking with code that has nsTArray
-+//! defined. Specifically, we must share the symbol for nsTArray's empty singleton. You will get
-+//! linking errors if that isn't defined.
-+//!
-+//! The gecko-ffi feature also limits ThinVec to the legacy behaviors of nsTArray. Most notably,
-+//! nsTArray has a maximum capacity of i32::MAX (~2.1 billion items). Probably not an issue.
-+//! Probably.

-commit 0b91f8a668201fc58fa732b8acc496caedfdbae0
-Author: Florian Weimer <fw@deneb.enyo.de>
-Date:   Sun Apr 29 12:18:33 2018 -0700

-    Indicate that _PyGC_Head is only 8-byte aligned. (closes bpo-33374)
-
-    By spec, the "long double" in _PyGC_Head requires the union to always be 16-byte
-    aligned. However, obmalloc only yields 8-byte alignment. Compilers including GCC
-    8 are starting to use alignment information to do store-merging. So, the "long
-    double" needs to be changed to a simple "double" as was long ago done in Python
-    3 by e348c8d154cf6342c79d627ebfe89dfe9de23817. For 2.7, we need to add some
-    dummy padding to make sure _PyGC_Head stays the same size.
