Crate sqlite_containers 

SQLite-based containers for Rust

sqlite-containers provides hash set and hash map implementations that are backed by SQLite in-memory databases.

Leveraging the power of the SQLite engine, these containers can efficiently store billions of elements.

Quick Start

This example demonstrates how to use SQLiteSet:

use sqlite_containers::SQLiteSet;

let mut sqlite_set = SQLiteSet::new().expect("Failed to create SQLiteSet!");
let mut tx = sqlite_set.transaction().expect("Failed to init transaction!");

println!("Inserting elements, please wait...");

for n in 0..1_000_000u64 {
    tx.insert(&format!("{:016X}", n)).expect("Insertion failed!");
}

tx.commit();
println!("{} element(s) successfully inserted.", sqlite_set.len().unwrap());
