Method trampoline_func_ref

crates/wasmtime/src/runtime/vm/component.rs:485–496

Returns the core wasm `funcref` corresponding to the trampoline specified. The returned function is suitable to pass directly to a wasm module instantiation and the function contains cranelift-compiled trampolines. This can only be called after `idx` has been initialized at runtime during the instantiation process of a component.
