Expand description

The result of compiling a WebAssembly module’s functions.

Fields§

§functions: Functions

Compiled code for the function bodies.

§custom_sections: CustomSections

Custom sections for the module. It will hold the data, for example, for constants used in a function, global variables, rodata_64, hot/cold function partitioning, …

§function_call_trampolines: PrimaryMap<SignatureIndex, FunctionBody>

Trampolines to call a function defined locally in the wasm via a provided Vec of values.

This allows us to call easily Wasm functions, such as:

let func = instance.exports.get_function("my_func");
func.call(&[Value::I32(1)]);
§dynamic_function_trampolines: PrimaryMap<FunctionIndex, FunctionBody>

Trampolines to call a dynamic function defined in a host, from a Wasm module.

This allows us to create dynamic Wasm functions, such as:

fn my_func(values: &[Val]) -> Result<Vec<Val>, RuntimeError> {
    // do something
}

let my_func_type = FunctionType::new(vec![Type::I32], vec![Type::I32]);
let imports = imports!{
    "namespace" => {
        "my_func" => Function::new(&store, my_func_type, my_func),
    }
}

Note: Dynamic function trampolines are only compiled for imported function types.

§unwind_info: UnwindInfo

Section ids corresponding to the unwind information.

§got: GOT

A reference to the GOT instance for the compilation.

Trait Implementations§
