RustDB

A simple key-value store à la Redis, implemented in pure Rust. Uses linear hashing for a dynamically-resizeable hash table. Supports serialization to disk along with a websocket interface.

Note: this was written mainly for fun and learning, not for production use!

Usage

Start the server using.

cargo run --bin server

Then, start the client using.

cargo run --bin client

On the client side, you can use the following commands:

• GET <key>: get the value of a key
• SET <key> <value>: set the value of a key
• INC <key>: increment the value of a key
• DEC <key>: decrement the value of a key
• SAVE: save the database to disk
• EXIT: exit the client
• HELP: show this help message

Keys are allowed to be arbitrary strings, and values are allowed to be strings, integers, or arrays of values.

Example:

> hello
WORLD
> get foo
(nil)
> set bar 10
OK
> inc bar
OK
> get bar
(integer) 11
> save
OK
