Rpc-Lib compiles a definition of RPC-Functions in the SUN-RPC format into Rust-code and provides necessary network-code to run the application. It follows the standard RFC-5531.

• Write the RPC-Definition in the SUN-RPC Format
• Create the server-application. This can be done in C with rpcgen
• Make sure the Portmapper-service is installed and running before starting the server-application

The following example shows how to use Rpc-Lib.

# Cargo.toml
[package]
name = "rpc-math"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
rpc-lib = { git = "https://git.rwth-aachen.de/acs/public/virtualization/rpc-lib/rpc-lib"}

/* math.x */
program MATH {
    version VERS_1 {
        int ADD(int, int) = 1;
    } = 1;
} = 67908;

// src/main.rs
use rpc_lib::include_rpcl;

#[include_rpcl("math.x")]
struct RPCStruct;

fn main() {
    let mut rpc = RPCStruct::new("127.0.0.1").expect("Server not available");

    let result = rpc.ADD(&1, &2).expect("Rpc call failed");

    assert!(result == 3, "Add failed");
}
