Tue, 31 Mar 2026 22:56:28 +0000

Exceptions: implement C API. (#12861)* Exceptions: implement C API.This PR implements C (and C++) API support for Wasm exceptions, onefinal remaining hurdle (aside from fuzz-testing) for making exceptionstier-1 and on-by-default.* Review feedback, and add exnref case to `wasmtime_val_t`.* Review feedback: GC feature guard.* clang-format* add docs to exn.hh.* Remove tag size asserts: broken on 32-bit platforms, but not needed for correctness wrt C struct.

eaa01d7b - [docs] Add C++ chapter and missing examples (#11569)

Tue, 02 Sep 2025 16:34:49 +0000

[docs] Add C++ chapter and missing examples (#11569)* [docs] Add C++ chapter and missing examplesThis adds a chapter for C++ embedding. The chapter intro is rudimentary, but there are a bunch more examples now: I added C++ ports for everything that already had both a Rust and a C version available, matching the Rust version's behavior where applicable.* [example] Fix paths in `examples/wasip1/main.c`* [docs] Add entries for additional Rust and C embedding examplesThese examples already existed, but didn't have entries in the docs.It'll probably make sense to restructure all of this at some point and move the examples into language-specific folders.* [docs] Remove references to Conan packages from README.mdThese packages haven't been updated since Wasmtime 18, so we shouldn't link to them for now.* Format cpp files* Format even more cpp files* Fix some warnings in C++ headers* Simplify threads.cc example* Update docs/examples-c-serialize.mdCo-authored-by: Nick Fitzgerald * [example] Don't try, do.* [docs] Restore CMake link in README* [docs] Improve examples/README.md* [docs] Address review feedback---------Co-authored-by: Alex Crichton Co-authored-by: Nick Fitzgerald List of files: /wasmtime-44.0.1/crates/c-api/include/wasmtime.hh

a045eaa9 - Run `clang-format` over more files (#10689)

Mon, 28 Apr 2025 20:38:14 +0000

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. List of files: /wasmtime-44.0.1/crates/c-api/include/wasmtime.hh

453bb9a4 - Split C++ Func/Table/Memory/Global to their own headers (#10688)

Mon, 28 Apr 2025 19:41:13 +0000

Split C++ Func/Table/Memory/Global to their own headers (#10688)I did my best to separate out headers but I don't understand enough C++to fully sever `val.hh` and `func.hh` so they sort of circularlyreference each other now. List of files: /wasmtime-44.0.1/crates/c-api/include/wasmtime.hh

ebc25c84 - Split out some more C++ types to their own headers (#10658)

Split out some more C++ types to their own headers (#10658)* Move C++ WASI configuration to its own header* Move C++ `Store` to its own fileI tried binding `wasmtime_store_epoch_deadline_callback` in C++ but Idon't know enough C++ to figure out the syntax for doing so.* Move C++ Val to its own headerAlso bind `AnyRef` while I'm here with some small tests.

0467d6f9 - Sketch out merging the C/C++ APIs (#10600)

Mon, 21 Apr 2025 20:47:20 +0000

Sketch out merging the C/C++ APIs (#10600)* Sketch out merging the C/C++ APIsWith the merging of the C++ API into this repository in #10582 it opensup some interesting questions about how to organize the C++ API.Externally it was all entirely a single file, but naturally this isn'tgreat for evolution as it's just one giant tangled header. Instead thiscommit sketches out a possible different path forward which is toprovide the C++ API as a sibling to the C API in preexisting headerfiles. For example this moves the `Error` class to the `error.h` headerfile as an example.My rough hope would be that in the long-term we could deprecate/removethe `wasmtime.hh` header file and instead "just" have all the C++ APIsin the normal header files (e.g. `wasmtime.h`). Additionally the splitof the C API in separate header files would be amenable to a similarsplit of the C++ API too where the API you see is basically conditionalon the language mode of whatever's including the headers.I'll note though I've not seen prior art in doing this. I'm not aware ofany other project which exports both a C and C++ API in its headerfiles. That being said I'm not sure how many other projects would fallin such a bucket.* Split out `error.hh` to its own file List of files: /wasmtime-44.0.1/crates/c-api/include/wasmtime.hh
