tideorm 0.9.4

//! Database connection and pool management
//!
//! This module exposes the `Database` handle used by query builders, model
//! helpers, and transactions.
//!
//! If database calls fail early, the most common causes are:
//! - the global database was never initialized with `Database::init()` or
//!   `Database::set_global()`
//! - the connection URL is wrong for the selected backend
//! - the current code is running outside the transaction or database scope you
//!   expected
//!
//! Use `Database::connect()` for straightforward setup. Use
//! `Database::builder()` when you need to adjust pool limits or timeouts.
//!
//! Practical split:
//! - use `Database::connect()` when you already know the URL and defaults are fine
//! - use `Database::builder()` when pool sizing, idle counts, or timeouts need tuning
//! - use the global handle only after startup initialization is finished, otherwise model helpers fail before they ever reach the backend
//!
//! If a query unexpectedly uses the wrong connection, check whether code is
//! still inside the intended transaction scope or whether it fell back to the
//! global handle.
