Struct rpc_toy::Server

pub struct Server { /* fields omitted */ }

A struct representing an RPC server, this is to be used to implement the server.

Implementations

impl Server

pub fn new() -> Self

Creates a new RPC server

pub fn register<F>(&mut self, fn_name: &str, function: F) where
    F: Fn(&[Value]) -> Option<Value> + 'static + Send, 

Registers functions to be used in the RPC server only functions registered using this function can be called from the client

Arguments:

• fn_name the name of the function to register, this MUST be the same name the client expects to use
• function the function to run once the RPC is invoked

Example:

use rpc_toy::Server;
let mut server = Server::new();
server.register("Add", |args| {
    let one = args.get(0).unwrap();
    let two = args.get(1).unwrap();
    let one = serde_json::from_value::<u32>(one.clone()).unwrap();
    let two = serde_json::from_value::<u32>(two.clone()).unwrap();
    let three = one + two;
    return Some(serde_json::to_value(three).unwrap());
});

pub fn listen(&self, addr: &str) -> Result<(), Error>

Listen to RPC connections This function must be run in order to start listening for calls over the network

Arguments:

• addr: An address to bind to, must be in the form: "host:port"

Examples:

use rpc_toy::Server;
let mut server = Server::new();
server.listen("127.0.0.1:3001").unwrap();
