Binmod MDK Rust

Rust binmod module development kit (MDK).

Quick Start

Installation

cargo add binmod-mdk

Basic Usage

use binmod_mdk::{mod_fn, host_imports, FnResult};

#[host_imports(namespace = "test")]
unsafe extern "host" {
    fn host_log(message: String);
    fn host_add(a: u32, b: u32) -> u32;
}

// NOTE: Function parameters and return types must be serializable. All module functions
// should return a `FnResult<T>` where `T` is the return type.
#[mod_fn(name = "greet")]
fn greet_impl(name: String, number: u32) -> FnResult<String> {
    unsafe { host_log(format!("Hello, {}! Your number is: {}", name, number))? };
    Ok(format!("Hello, {}! Your number is: {}", name, number))
}

Compiling

Finally, compile your module to the wasm32-wasip1 target:

rustup target add wasm32-wasip1
cargo build --target wasm32-wasip1 --release
