zrpc
Minimal RPC for Rust
- Only what is shown in examples works, nothing more.
Design goals
- Non-forcing. You just write your api, put
#[rpc]and it just works! - Very minimal, cnvention over configuration.
- Multi-transport
- Async/await
- Server references! Zero-copy! and much more!
Easy to use
See examples/minimal
Server references
Imagine there are two entities A and B. We invoke rpc get_item(a_id) -> A. We also have a method generate_b(&A).
We can avoid all the data from A having to go from server to client if we invoke something like generate_b(get_item(1)) by first returning lazy server reference from get_item and dereferencing by passing actual data of A only when required.
Zero-copy
When you have something like this signature in your rpc:
fn apply(&mut self, raw: &[u8]);you'll work directly with the buffer from network!
