# wasmer

`wasmer` is a wrapper over Wasmer C API. This module not only provides access to the C API but it also strives to provide easy to use wrappers over the C API.

# Example usage

```v

import wasmer

fn main() {

    engine := wasmer.engine()

    store := wasmer.store(engine)

    wasm := wasmer.wat2wasm('(module

        (func \$add (param \$lhs i32) (param \$rhs i32) (result i32)

            local.get \$lhs

            local.get \$rhs

            i32.add)

        (export "add" (func \$add))

    

    )')?

    mod := wasmer.compile(store,wasm)?

    imports := wasmer.extern_vec_empty()

    mut trap := wasmer.Trap{}

    instance := wasmer.instance(store,mod,imports,mut trap)

    func := instance.exports().at(0).as_func()?

    mut results := [wasmer.val_i32(0)]

    trap = func.call([wasmer.val_i32(2),wasmer.val_i32(3)],mut results)

    if trap.is_set() {

        println(trap.message()?)

    } else {

        println(results[0])

    }

    engine.delete()

    trap.delete()

    store.delete()

}

```
