Caves

A collection of embedded, thread-safe key-value stores (kvs) in Rust.

Overview

The caves crate provides a selection of key-value stores with the following features:

• [Embedded]
• Thread-safe
• Simple API; get/set/delete a key
• Dev-friendly

You can find more info on the rationale behind this crate on https://docs.rs/caves.

Usage

```rust use caves::errors::Error; use caves::{MemoryCave, Cave};

// Initialize a MemoryCave object. let b = MemoryCave::new();

// Create a new key with an empty value. b.set("key", b"");

// Override the key's value. b.set("key", b"value");

// Retrieve the contents of the key. let res = b.get("key"); assert_eq!(res.unwrap(), b"value");

// Delete the key. b.delete("key");

// Subsequent attempts to retrieve the contents of the key should return an // error. let res = b.get("key"); asserteq!(res, Err(Error::NotFound("key".tostring()))); ```

The above example uses an in-memory backend, but there is also support for filesystem and RocksDB backends. The latter can be enabled by passing the with-rocksdb feature flag for the caves dependency in your Cargo.toml.
