Wasmtime GitHub notifications bot (Mar 05 2023 at 22:32): Wasmtime GitHub notifications bot (Mar 05 2023 at 22:32):dicej opened PR #5934 from wit-templates-minimal to main:
templates, allowing WIT files to define interfaces which contain a single wildcard function, which worlds may import or export.
I've taken a "minimalist" approach to this, such that the host binding generator just skips wildcards entirely, leaving it to the host to use dynamic APIs to reflect on the component and do the necessary func_wrap (for imports) and typed_func (for exports) calls directly.
This adds two new functions to the public API:
Component::names: provides an iterator over the names of the functions imported by the specified instance.ExportInstance::funcs: provides an iterator over the names of the functions exported by this instance.In both cases, I'm open to alternative API designs for getting that information.
Note that I've added a temporary dependency override to Cargo.toml, pointing to our fork of wasm-tools, which includes the necessary wit-parser changes. We're still iterating on that and will PR those changes separately. We also have a fork of wit-bindgen with a new "wildcards" test to verify everything works end-to-end: https://github.com/bytecodealliance/wit-bindgen/compare/main...dicej:wit-templates. I'll PR that last once everything else is stable.
