* add pub sub client implementation with examples * replace subscribed_channels list Vec with HashSet to avoid duplicates * update Subscriber to use async-stream instead of manual Stream impl * revert update to error handling server.rs, as #21 handles it * remove uneeded recursion limit extension

//! 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 server
|
|
//!
|
|
//! Then in another terminal run:
|
|
//!
|
|
//! cargo run --example sub
|
|
//!
|
|
//! And then in another terminal run:
|
|
//!
|
|
//! cargo run --example pub
