§TegDB - A high-performance, embedded database engine
TegDB provides a high-level SQLite-like database interface for easy database operations.
§Database API
The Database struct provides a SQLite-like interface for easy database operations:
use tegdb::{Database, Result};
// Open or create a database
let mut db = Database::open("my_database.db")?;
// Create table
db.execute("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, age INTEGER)")?;
// Insert data
db.execute("INSERT INTO users (id, name, age) VALUES (1, 'Alice', 30)")?;
// Query data
let result = db.query("SELECT * FROM users")?.into_query_result()?;
for row in result.rows() {
println!("User row: {:?}", row);
}
// Use transactions
let mut tx = db.begin_transaction()?;
tx.execute("UPDATE users SET age = 31 WHERE id = 1")?;
tx.commit()?;
§Low-level API (Advanced Users)
For advanced use cases, benchmarks, or examples, you can enable the dev feature
to access the low-level engine API:
[dependencies]
tegdb = { version = "0.2", features = ["dev"] }This exposes additional types like Engine, EngineConfig, Executor, etc.
for direct engine manipulation.
