* 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
This commit is a mirror of bytecodealliance/wit-bindgen#547 into the
`bindgen!` macro for Wasmtime. The new default is to generate only one
Rust type per WIT type input, regardless of if the representation can be
slightly more optimal in niche cases with more borrows. This should make
the macro easier to work with in the limit ideally.
Closes#6124
This follows the same strategy pioneered by the `wit-bindgen` guest Rust
bindgen which keeps track of the latest name of an interface for how to
refer to an interface.
Closes#5961
* 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.
* Update world-selection in `bindgen!` macro
Inspired by bytecodealliance/wit-bindgen#494 specifying a world or
document to bindgen is now optional as it's inferred if there's only one
`default world` in a package's documents.
* Add cargo-vet entry
* 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
This commit fixes a bug in the `bindgen!` macro for components where
previously the `param` and `result` properties weren't properly
calculated depending on the structure of the type and which types were
visited in which order. This is simplified to use a `LiveTypes`
structure from the `wit-parser` crate and relies on that to do necessary
recursion.
* 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
* Import Wasmtime support from the `wit-bindgen` repo
This commit imports the `wit-bindgen-gen-host-wasmtime-rust` crate from
the `wit-bindgen` repository into the upstream Wasmtime repository. I've
chosen to not import the full history here since the crate is relatively
small and doesn't have a ton of complexity. While the history of the
crate is quite long the current iteration of the crate's history is
relatively short so there's not a ton of import there anyway. The
thinking is that this can now continue to evolve in-tree.
* Refactor `wasmtime-component-macro` a bit
Make room for a `wit_bindgen` macro to slot in.
* Add initial support for a `bindgen` macro
* Add tests for `wasmtime::component::bindgen!`
* Improve error forgetting `async` feature
* Add end-to-end tests for bindgen
* Add an audit of `unicase`
* Add a license to the test-helpers crate
* Add vet entry for `pulldown-cmark`
* Update publish script with new crate
* Try to fix publish script
* Update audits
* Update lock file
