1//! Configuration types for storage initialization.
2//!
3//! This module provides config structs that allow components to be initialized
4//! with sensible defaults while still allowing customization when needed.

10/// Configuration for storage backends.
11///
12/// This struct allows components to configure storage without needing to know
13/// implementation details like SQLite. Users provide *what* they want (path, options),
14/// not *how* it's implemented.
15///
16/// # Example
17///
18/// ```
19/// use mi6_core::StorageConfig;
20///
21/// // Use defaults (reads from MI6_DIR_PATH or ~/.mi6)
22/// let config = StorageConfig::default();
23///
24/// // Custom database path
25/// let config = StorageConfig {
26///     db_path: Some("/tmp/test.db".into()),
27///     ..Default::default()
28/// };
29/// ```
