Fork

NOTE: This fork was exclusivly created for the following upstream PR: https://github.com/aembke/redis-protocol.rs/pull/21

This crate will get deleted once the upstream PR has been merged and published!

lib.rs:

Redis Protocol

Structs and functions for implementing the RESP2 and RESP3 protocol.

Examples

use redis_protocol::resp2::prelude::*;
use bytes::{Bytes, BytesMut};

fn main() {
  let frame = Frame::BulkString("foobar".into());
  let mut buf = BytesMut::new();

  let len = match encode_bytes(&mut buf, &frame) {
    Ok(l) => l,
    Err(e) => panic!("Error encoding frame: {:?}", e)
  };
  println!("Encoded {} bytes into buffer with contents {:?}", len, buf);

  let buf: Bytes = "*3\r\n$3\r\nFoo\r\n$-1\r\n$3\r\nBar\r\n".into();
  let (frame, consumed) = match decode(&buf) {
    Ok(Some((f, c))) => (f, c),
    Ok(None) => panic!("Incomplete frame."),
    Err(e) => panic!("Error parsing bytes: {:?}", e)
  };
  println!("Parsed frame {:?} and consumed {} bytes", frame, consumed);

  let key = "foobarbaz";
  println!("Hash slot for {}: {}", key, redis_keyslot(key.as_bytes()));
}

Note: if callers are not using the index-map feature then substitute std::collections::HashMap for any IndexMap types in these docs. rustdoc doesn't have a great way to show type substitutions based on feature flags.
