* Add `only_interfaces` and `with` to the `bindgen!` macro.
* Add a version of the empty_error test for `only_interfaces` and `with`
* Review feedback
* Add docs
* Change the name of wit-bindgen's host implementation traits.
Instead of naming the host implementation trait something like
`wasi_filesystem::WasiFilesystem`, name it `wasi_filesystem::Host`, and
avoid using the identifier `Host` in other places.
This fixes a collision when generating bindings for the current
wasi-clock API, which contains an interface `wall-clock` which contains
a type `wall-clock`, which created a naming collision on the name
`WallClock`.
* Update tests to use the new trait name.
* Fix one more.
* Add the new test interface to the simple-wasi world.
* Prefix component-bindgen-generated-functions with `call_`
This fixes clashes between Rust-native methods and the methods
themselves. For example right now `new` is a Rust-generated function for
constructing the wrapper but this can conflict with a world-exported
function called `new`.
Closes#5585
* Fix types being both shared and owned
This refactors some inherited cruft from the original `wit-bindgen`
repository to be more Wasmtime-specific and fixes a codegen case where
a type was used in both a shared and an owned context.
Closes#5688
* Update WIT tooling used by Wasmtime
This commit updates the WIT tooling, namely the wasm-tools family of
crates, with recent updates. Notably:
* bytecodealliance/wasm-tools#867
* bytecodealliance/wasm-tools#871
This updates index spaces in components and additionally bumps the
minimum required version of the component binary format to be consumed
by Wasmtime (because of the index space changes). Additionally WIT
tooling now fully supports `use`.
Note that WIT tooling doesn't, at this time, fully support packages and
depending on remotely defined WIT packages. Currently WIT still needs to
be vendored in the project. It's hoped that future work with `cargo
component` and possible integration here could make the story about
depending on remotely-defined WIT more ergonomic and streamlined.
* Fix `bindgen!` codegen tests
* Add a test for `use` paths an implement support
* Update to crates.io versions of wasm-tools
* Uncomment codegen tests
* wip
* start trying to write a runtime test
* cut out all the more complex test cases until i get this one working
* add macro parsing for the trappable error type config
* runtime result tests works for an empty and a string error type
* debugging: macro is broken because interfaces dont have names???
* thats how you name interfaces
* record error and variant error work
* show a concrete trap type, remove debug
* delete clap annotations from wit-bindgen crate
these are not used - clap isnt even an optional dep here - but were a holdover from the old home
