A high-level UnQLite database engine wrapper.

NOTE: Some of the documents is stolen fromUnQLite Official Website.

UnQLite is a software library which implements aself-contained,serverless,zero-configuration, transactional NoSQL database engine. UnQLite is a document store databasesimilar to [MongoDB], [Redis], [CouchDB] etc. as well a standard Key/Value store similar to[BerkeleyDB], [LevelDB], etc.

UnQLite is an embedded NoSQL (Key/Value store and Document-store) database engine. Unlike mostother NoSQL databases, UnQLite does not have a separate server process. UnQLite reads andwrites directly to ordinary disk files. A complete database with multiple collections, iscontained ina single disk file. The database file format is cross-platform, you can freelycopy a database between 32-bit and 64-bit systems or between big-endian and little-endianarchitectures.

This crate is high-level UnQLite database wrapper for Rust. A low-level bindings wrapperis available as a seperated crate:unqlite-sys.

You can start withUnQLite constructors:

externcrate unqlite;use unqlite::{UnQLite,Config,KV,Cursor};fnmain(){// The database memory is not handled by Rust, and the database is on-disk,// so `mut` is not neccessary.let unqlite =UnQLite::create_temp();// Use any type that can use as `[u8]`    unqlite.kv_store("key","a long length value").unwrap();    unqlite.kv_store("abc",[1,2,3]).unwrap();letmut entry = unqlite.first();// Iterate recordsloop{if entry.is_none(){break;}let record = entry.expect("valid entry");let(key, value) = record.key_value();println!("* Go through {:?} --> {:?}", key, value);if value.len() >10{println!("** Delete key {:?} by value length", key);            entry = record.delete();}else{            entry = record.next();}}//panic!("for test");}
