SRPC
SRPC is a simple RPC system built on top of Canary, designed to be as ergonomic and zero-cost as possible.
A simple example of an SRPC service
#[srpc::rpc] // other options include rpc(mutex), rpc(none)
#[derive(Default)]
struct DistributedList<T> {
list: Vec<T>
}
#[srpc::rpc]
impl<T: Clone> DistributedList<T> {
async fn push(&mut self, value: T) {
self.list.push(value);
}
async fn get(&self, index: usize) -> Option<T> {
self.list.get(index).and_then(|val| Some(val.clone()))
}
async fn remove(&mut self, index: usize) -> T {
self.list.remove(index)
}
}
// database
async fn main() -> Result<()> {
GLOBAL_ROUTE.add_service_at::<DistributedList<i32>>("list", Arc::new(RwLock::new(Default::default())))?;
let addr = "tcp@127.0.0.1:8080".parse::<Addr>()?;
// listen in the following address
addr.bind().await?;
std::future::pending().await
}
// peer
async fn main() -> Result<()> {
let addr = "list://tcp@127.0.0.1:8080".parse::<ServiceAddr>()?;
let connection = addr.connect().await?;
let mut db = connection.client::<DistributedList<i32>>();
db.push(1).await?;
db.push(5).await?;
db.push(6).await?;
let value = db.get(1).await?;
println!("{:?}", value); // index 1 == 5
Ok(())
}
SRPC also allows method attributes for flexibility. The current attributes you can apply to methods are:
#[consume]
#[server_consume]
#[client_consume]
#[server]
