Generic value log implementation for key-value separated storage, inspired by RocksDB's BlobDB [1] and implemented in safe, stable Rust.

This crate is intended as a building block for key-value separated storage. You probably want to use https://github.com/fjall-rs/fjall instead.

• Thread-safe API
• 100% safe & stable Rust
• Supports generic KV-index structures (LSM-tree, ...)
• Generic per-blob compression (optional)
• In-memory blob cache for hot data (can be shared between multiple value logs to cap memory usage)
• On-line garbage collection

Keys are limited to 65536 bytes, values are limited to 2^32 bytes.

Enables serde derives.

Disabled by default.

The disk format is stable as of 1.0.0. Future breaking changes will result in a major version bump and a migration path.
