Declare the database URL:

export DATABASE_URL="sqlite:///path/to/this/directory/todos.db"

Create the database:

sqlite3 todos.db

Load the database schema (using the SQLite CLI interface opened from the previous command):

sqlite> .read schema.sql

Use .exit to leave the SQLite CLI. Then, to run this example:

• Add a todo: cargo run -- add "todo description"
• Complete a todo: cargo run -- done <todo id>
• List all todos: cargo run
