Fred

An async Redis client for Rust and Tokio.

Example

use fred::prelude::*;

#[tokio::main]
async fn main() -> Result<(), RedisError> {
  let client = RedisClient::default(); 
  client.init().await?;

  // convert responses to many common Rust types
  let foo: Option<String> = client.get("foo").await?;
  assert!(foo.is_none());

  client.set("foo", "bar", None, None, false).await?;
  // or use turbofish to declare response types
  println!("Foo: {:?}", client.get::<String, _>("foo").await?);

  // or use a lower level interface for responses to defer parsing, etc
  let foo: RedisValue = client.get("foo").await?;
  assert_eq!(foo.as_str().unwrap(), "bar");

  client.quit().await?;
  Ok(())
}
