e98f2c

e98f2c
+//! This makes the memory footprint of ThinVecs lower; notably in cases where space is reserved for
e98f2c
+//! a non-existence ThinVec<T>. So `Vec<ThinVec<T>>` and `Option<ThinVec<T>>::None` will waste less

e98f2c
+//!
e98f2c
+//! If you enable the gecko-ffi feature, ThinVec will verbatim bridge with the nsTArray type in
e98f2c
+//! Gecko (Firefox). That is, ThinVec and nsTArray have identical layouts *but not ABIs*, 
e98f2c
+//! so nsTArrays/ThinVecs an be natively manipulated by C++ and Rust, and ownership can be 
e98f2c
+//! transferred across the FFI boundary (**IF YOU ARE CAREFUL, SEE BELOW!!**).
e98f2c
+//!
e98f2c
+//! While this feature is handy, it is also inherently dangerous to use because Rust and C++ do not
e98f2c
+//! know about eachother. Specifically, this can be an issue with non-POD types (types which
e98f2c
+//! have destructors, move constructors, or are `!Copy`).
e98f2c
+//!
e98f2c
+//! ## Do Not Pass By Value
e98f2c
+//!
e98f2c
+//! The biggest thing to keep in mind is that **FFI functions cannot pass ThinVec/nsTArray 
e98f2c
+//! by-value**. That is, these are busted APIs:

e98f2c
+//!
e98f2c
+//! > The fundamental issue is that Rust and C++ can't currently communicate about destructors, and
e98f2c
+//! > the semantics of C++ require destructors of function arguments to be run when the function
e98f2c
+//! > returns. Whether the callee or caller is responsible for this is also platform-specific, so
e98f2c
+//! > trying to hack around it manually would be messy. 
e98f2c
+//! >
e98f2c
+//! > Also a type having a destructor changes its C++ ABI, because that type must actually exist 
e98f2c
+//! > in memory (unlike a trivial struct, which is often passed in registers). We don't currently
e98f2c
+//! > have a way to communicate to Rust that this is happening, so even if we worked out the

e98f2c
+//! ## Types Should Be Trivially Relocatable
e98f2c
+//!
e98f2c
+//! Types in Rust are always trivially relocatable (unless suitably borrowed/[pinned][]/hidden).
e98f2c
+//! This means all Rust types are legal to relocate with a bitwise copy, you cannot provide
e98f2c
+//! copy or move constructors to execute when this happens, and the old location won't have its
e98f2c
+//! destructor run. This will cause problems for types which have a significant location
e98f2c
+//! (types that intrusively point into themselves or have their location registered with a service).
e98f2c
+//!
e98f2c
+//! While relocations are generally predictable if you're very careful, **you should avoid using
e98f2c
+//! types with significant locations with Rust FFI**.
e98f2c
+//!
e98f2c
+//! Specifically, ThinVec will trivially relocate its contents whenever it needs to reallocate its
e98f2c
+//! buffer to change its capacity. This is the default reallocation strategy for nsTArray, and is
e98f2c
+//! suitable for the vast majority of types. Just be aware of this limitation!
e98f2c
+//!
e98f2c
+//! ## Auto Arrays Are Dangerous
e98f2c
+//!
e98f2c
+//! ThinVec has *some* support for handling auto arrays which store their buffer on the stack, 
e98f2c
+//! but this isn't well tested.
e98f2c
+//!
e98f2c
+//! Regardless of how much support we provide, Rust won't be aware of the buffer's limited lifetime,
e98f2c
+//! so standard auto array safety caveats apply about returning/storing them! ThinVec won't ever
e98f2c
+//! produce an auto array on its own, so this is only an issue for transferring an nsTArray into
e98f2c
+//! Rust.
e98f2c
+//!
e98f2c
+//! ## Other Issues
e98f2c
+//!
e98f2c
+//! Standard FFI caveats also apply: 
e98f2c
+//!
e98f2c
+//!  * Rust is more strict about POD types being initialized (use MaybeUninit if you must)
e98f2c
+//!  * `ThinVec<T>` has no idea if the C++ version of `T` has move/copy/assign/delete overloads
e98f2c
+//!  * `nsTArray<T>` has no idea if the Rust version of `T` has a Drop/Clone impl
e98f2c
+//!  * C++ can do all sorts of unsound things that Rust can't catch
e98f2c
+//!  * C++ and Rust don't agree on how zero-sized/empty types should be handled
e98f2c
+//!
e98f2c
+//! The gecko-ffi feature will not work if you aren't linking with code that has nsTArray
e98f2c
+//! defined. Specifically, we must share the symbol for nsTArray's empty singleton. You will get
e98f2c
+//! linking errors if that isn't defined.
e98f2c
+//!
e98f2c
+//! The gecko-ffi feature also limits ThinVec to the legacy behaviors of nsTArray. Most notably,
e98f2c
+//! nsTArray has a maximum capacity of i32::MAX (~2.1 billion items). Probably not an issue.
e98f2c
+//! Probably.
