//! Subscribe to a redis channel example.
|
|
//!
|
|
//! A simple client that connects to a mini-redis server, subscribes to "foo" and "bar" channels
|
|
//! and awaits messages published on those channels
|
|
//!
|
|
//! You can test this out by running:
|
|
//!
|
|
//! cargo run --bin mini-redis-server
|
|
//!
|
|
//! Then in another terminal run:
|
|
//!
|
|
//! cargo run --example sub
|
|
//!
|
|
//! And then in another terminal run:
|
|
//!
|
|
//! cargo run --example pub
|
