Crate matdb 

An experimental embedded SQL-like DBMS featuring:

• Core SQL: SELECT, UPDATE, DELETE, INSERT
• Graph expressions - support for graph-style joins and navigation
• ACID compliance - fully transactional storage engine
• System catalogue - introspection via internal tables
• E-graph based query optimization - advanced rewrite and cost-based planning
• Time-traveling queries - access to full historical data versions

More about these features in the readme.

Typical library usage:

let mut db = Db::open("db.matdb".into())?;

db.run("CREATE TABLE messages (id INT PRIMARY KEY, body TEXT NOT NULL);", Vec::new())?;
db.run("INSERT INTO messages (id, body) VALUES (?0, ?1);", vec![1.into(), "Hello, matdb!".to_string().into()])?;
db.finish_tx()?;

assert_eq!(
    Value::String("Hello, matdb!".to_string()),
    db.run("SELECT body FROM messages WHERE id = 1;", Vec::new())?.unwrap().rows[0][0]
);
