Method func_untyped

crates/tinywasm/src/instance.rs:416–433

Get a function export by name. ## Example ```rust # fn main() -> tinywasm::Result<()> { # use tinywasm::{ModuleInstance, Store}; # use tinywasm::types::WasmValue; # let wasm = wat::parse_str(r#" # (module # (func (export "add") (param i32 i32) (result i32) # local.get 0 # local.get 1 # i32.add)) # "#).expect("valid wat"); # let module = tinywasm::parse_bytes(&was
