Rust wrapper for WASM3.
This is currently work in progress and may or may not be sound.
The crate has yet to be published on crates.io(there are a few things I wanna get done before publishing still), due to this one currently has to specify the crate as a git dependency:
[dependencies]
wasm3 = { git = "https://github.com/Veykril/wasm3-rs.git" }
A simple example that loads a wasm module and executes an exported function to add two i64
s together.
use wasm3::Environment;
use wasm3::Module;
fn main() {
let env = Environment::new().expect("Unable to create environment");
let rt = env
.create_runtime(1024 * 60)
.expect("Unable to create runtime");
let module = Module::parse(&env, &include_bytes!("wasm/wasm_add/wasm_add.wasm")[..])
.expect("Unable to parse module");
let module = rt.load_module(module).expect("Unable to load module");
let func = module
.find_function::<(i64, i64), i64>("add")
.expect("Unable to find function");
println!("Wasm says that 3 + 6 is {}", func.call(3, 6).unwrap())
}
This crate currently does not make use of the cmake project of wasm3, meaning cmake is not required to built this for the time being. It does however require Clang 9 to be installed as well as Bindgen.
