waPC Guest SDK

The waPC Guest SDK is used by Rust developers building workloads for the wasm32-unknown-unknown target that will conform to the waPC (WebAssembly Procedure Calls) specification.

This crate is used by waSCC as a foundation for its secure, dynamic binding of cloud capabilities on top of the waPC spec.

Example

extern crate wapc_guest as guest;

use guest::prelude::*;

#[no_mangle]
pub extern "C" fn wapc_init() {
  register_function("sample:Guest!Hello", hello_world);
}

fn hello_world(_msg: &[u8]) -> CallResult {
    let _res = host_call("myBinding", "sample:Host", "Call", b"hello")?;
    Ok(vec![])
}
