Module storage 

Storage abstraction layer for task persistence.

This module defines the Storage trait and re-exports two built-in implementations:

Type	Description
JsonStorage	Persists tasks to a JSON file in the OS data directory
InMemoryStorage	Stores tasks in memory — ideal for tests

Implementing a custom storage backend

Implement Storage to add your own persistence layer (SQLite, cloud sync, encrypted file, etc.):

use anyhow::Result;
use rustodo::models::Task;
use rustodo::storage::Storage;

struct MyStorage;

impl Storage for MyStorage {
    fn load(&self) -> Result<Vec<Task>> {
        // read from your backend
        Ok(vec![])
    }

    fn save(&self, tasks: &[Task]) -> Result<()> {
        // write to your backend
        Ok(())
    }

    fn location(&self) -> String {
        "my-backend".to_string()
    }
}
