//! Boot Chronon with a file-backed SQLite [`SchedulerStore`](chronon_core::SchedulerStore).
//!
//! Set `CHRONON_SQLITE_PATH` to a file path (default `/tmp/chronon-example.db`), or `:memory:`
//! for an ephemeral database.
//!
//! ```bash
//! cargo run -p uf-chronon --example sqlite_boot --features sqlite
//! CHRONON_SQLITE_PATH=:memory: cargo run -p uf-chronon --example sqlite_boot --features sqlite
//! ```
