Effectively a combination of bugs in the Rust API meant that itwasn't possible to use `externref` or `anyref` bindings correctly. TheRust changes in this commit are:* `wasmtime_val_unroot` correctly drops the value now as opposed to effectively being a noop from before (typo of using `as_externref` vs `from_externref`).* `wasmtime_{anyref,externref,val}_t` now have a `Drop` implementation in Rust to correctly drop them if a value in Rust is dropped. This is required to correctly manage memory in the `wasmtime_func_{call,new}` implementations, for example.* `wasmtime_{anyref,externref,val}_clone` no longer have an unnecessary context parameter.* `wasmtime_{anyref,externref,val}_unroot` no longer have an unnecessary context parameter.Changes in the C/C++ APIs are:* `Result::{ok,err}_ref` APIs were added in addition to the preexisting rvalue accessors.* Loading/storing typed arguments now has an overload for `const T&` and `T&&` which behaves differently. Notably transferring ownership for `T&&` and not for `const T&`. This means that passing parameters when calling a wasm function uses `const T&`, but passing results from a host import uses `T&&`.* `TypedFunc::call` now uses `const Params&` instead of `Params` to explicitly specify it doesn't modify the parameters and forces using the `const T&` store method.* `Store::gc` is now a convenience method for `store.context().gc()`* `ExternRef`, `AnyRef`, and `Val` now have ownership semantics and destructors. This matches the spirit of #11514 for Rust but models it in C++ as well. This required filling out move/copy constructors/assignments.* The explicit `ExternRef` now takes `std::any` instead of `T`.* Minor issues related to ownership are fixed in `Val` bindings.Valgrind was used to ensure that there were no leaks for the test suitewhich additionally resulted in a number of `*_delete` calls being addedto tests using the C API (accidental omissions).The original goal of this change was to be a patch release for 37.0.1 toenable updating wasmtime-py to the 37.0.x releases of Wasmtime. In theend though the changes here were broad enough that I no longer feel thatthis is a good idea, so wasmtime-py will be skipping the 37 version ofWasmtime.* Run `clang-format`prtest:full List of files: /wasmtime-44.0.1/crates/c-api/tests/simple.cc Tue, 07 Oct 2025 16:36:13 +0000 Alex Crichton <alex@alexcrichton.com> http://172.16.0.5:8080/history/wasmtime-44.0.1/crates/c-api/tests/simple.cc#3a5dda5f Split final C++ items out of `wasmtime.hh` (#10692)* Split final C++ items out of `wasmtime.hh`Now `wasmtime.hh` is just an "amalgamation" header to includeeverything, yay!* Format files* Try to fix MSVC List of files: /wasmtime-44.0.1/crates/c-api/tests/simple.cc Mon, 28 Apr 2025 23:39:04 +0000 Alex Crichton <alex@alexcrichton.com> http://172.16.0.5:8080/history/wasmtime-44.0.1/crates/c-api/tests/simple.cc#a045eaa9 Run `clang-format` over more files (#10689)We were already running it over most `*.c` files and other ones butforgot the `*.hh` and `*.cc` extensions which are being used for C++bindings, so add those in and then run the formatter.
