WASM Plugins

High-performance plugins using WebAssembly.

Overview

WASM plugins provide:

• Cross-language compatibility
• Sandboxed execution
• Near-native performance

Creating a WASM Plugin

Setup

# Cargo.toml
[lib]
crate-type = ["cdylib"]

[dependencies]
wasm-bindgen = "0.2"

Implementation

#![allow(unused)]
fn main() {
use wasm_bindgen::prelude::*;

#[wasm_bindgen]
pub fn process(input: &str) -> String {
    // Your implementation
    format!("Processed: {}", input)
}

#[wasm_bindgen]
pub fn analyze(data: &[u8]) -> Vec<u8> {
    // Binary data processing
    data.to_vec()
}
}

Build

cargo build --target wasm32-unknown-unknown --release

Loading WASM Plugins

#![allow(unused)]
fn main() {
use mofa_plugins::WasmPlugin;

let plugin = WasmPlugin::load("./plugins/my_plugin.wasm").await?;

// Call exported function
let result = plugin.call("process", b"input data").await?;
println!("Result: {}", String::from_utf8_lossy(&result));
}

Security

WASM plugins run in a sandboxed environment:

• No direct file system access
• No network access (unless explicitly granted)
• Memory isolation
