PoloDB is a library written in Rust that implements a lightweight MongoDB. Why
PoloDB aims to offer a modern alternative to SQLite, which is currently the almost exclusive option for client-side data storage. Although SQLite is an old and stable software, it lacks some modern features. That's why we developed PoloDB, which is NoSQL, supports multi-threading and multi-sessions, and retains the embedded and lightweight features of SQLite. Features Simple and Lightweight can be embedded library or a standalone server Easy to learn and use NoSQL MongoDB-like API Cross-Platform Quick start
```rust use polodbcore::Database; use serde::{Serialize, Deserialize};
