Redis and Rust

A Brief Introduction to Rust

Rust is blazingly fast and memory-efficient: with no runtime or garbage collector, it can power performance-critical services, run on embedded devices, and easily integrate with other languages. Rust’s rich type system and ownership model guarantee memory-safety and thread-safety — enabling you to eliminate many classes of bugs at compile-time.

Rust has great documentation, a friendly compiler with useful error messages, and top-notch tooling — an integrated package manager and build tool, smart multi-editor support with auto-completion and type inspections, an auto-formatter, and more.

Using Redis with Rust

Pre-requisite

• Install Rust on your Mac system

Rust is installed and managed by the rustup tool.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Configure your current shell:

source $HOME/.cargo/env

Verify Rust compiler:

rustc --version
rustc 1.49.0

• Install Redis

docker run --rm -p 6379:6379 redis

Steps

Clone the repository

git clone https://github.com/redis-developer/rust-redis-101
cd rust-redis-101

Export

If you’re using a local Redis server (e.g. with Docker) over an insecure connection without any password, simply use:

export REDIS_HOSTNAME=localhost:6379

Run the application

cargo run

Verify the Output

   Compiling redis-rust-getting-started v0.1.0 (/Users/ajeetraina/projects/rust-redis-101)
    Finished dev [unoptimized + debuginfo] target(s) in 0.70s
     Running `target/debug/rust-redis-101`
******* Running SET, GET, INCR commands *******
value for 'foo' = bar
counter = 16

Conclusion

Today you learned how to use the Rust driver for Redis to connect and execute operations in Redis.
