Macro wasm_init::wasm_init

macro_rules! wasm_init {
    ($($input:tt)*) => { ... };
}

Register code to be run on start-up.

Each call to this macro will generate a function that will be called exactly once, after the wasm_init function is called for the first time.

You can register code from as many different crates in your project as you’d like; wasm_init only needs to be called once.

Examples

trait Plugin {}

fn register_plugin(plugin: impl Plugin) {
	// grab data from each plugin and store them in a global somewhere
}

struct Plugin1;

wasm_init::wasm_init! {
	register_plugin(Plugin1);
}

struct Plugin2;

wasm_init::wasm_init! {
	register_plugin(Plugin2);
}
