Implementations

Get the WebAssembly type signature for this interface function

The first entry returned is the list of parameters and the second entry is the list of results for the wasm function signature.

Generates an abstract sequence of instructions which represents this function being adapted as an imported function.

The instructions here, when executed, will emulate a language with interface types calling the concrete wasm implementation. The parameters for the returned instruction sequence are the language’s own interface-types parameters. One instruction in the instruction stream will be a Call which represents calling the actual raw wasm function signature.

This function is useful, for example, if you’re building a language generator for WASI bindings. This will document how to translate language-specific values into the wasm types to call a WASI function, and it will also automatically convert the results of the WASI function back to a language-specific value.

This is the dual of InterfaceFunc::call_wasm, except that instead of calling a wasm signature it generates code to come from a wasm signature and call an interface types signature.
