things3-common 1.4.0

//! Things Common - Shared utilities and types for Things 3 integration
//!
//! This crate provides shared utilities and constants for Things 3 integration.
//!
//! # Examples
//!
//! ```
//! use things3_common::{DATABASE_FILENAME, truncate_string, format_date};
//! use chrono::NaiveDate;
//!
//! // Use constants
//! assert_eq!(DATABASE_FILENAME, "main.sqlite");
//!
//! // Use utility functions
//! let truncated = truncate_string("hello world", 5);
//! assert_eq!(truncated, "he...");
//!
//! let date = NaiveDate::from_ymd_opt(2023, 12, 25).unwrap();
//! let formatted = format_date(&date);
//! assert_eq!(formatted, "2023-12-25");
//! ```
