defmodule Wasmex do
@moduledoc """
Wasmex is an Elixir library for executing WebAssembly binaries.
WASM files can be executed using a WebAssembly `Wasmex.Instance`:
```elixir
{:ok, bytes } = File.read("wasmex_test.wasm")
{:ok, instance } = Wasmex.Instance.from_bytes(bytes)
instance
|> Wasmex.Instance.call_exported_function("sum", [50, -8])
```
Memory can be read/written using `Wasmex.Memory`:
```elixir
offset = 7
index = 4
value = 42
{:ok, memory} = Wasmex.Instance.memory(instance, :uint8, offset)
Wasmex.Memory.set(memory, index, value)
IO.puts Wasmex.Memory.get(memory, index) # 42
```
