1//! Error module.
2//!
3//! ## Overview
4//! This module contains the unified error types for the DS Common AWS Rust Library.
5//! All functions return `Result<T, Error>` for consistent error handling.
6//!
7//! ## Error Hierarchy
8//!
9//! - [`Error`]: Top-level error enum that unifies all module errors
10//! - [`SsmError`]: Errors from SSM operations
11//! - [`SqsError`]: Errors from SQS operations
12//!

29/// Top-level error enum that unifies all module errors.
30///
31/// This enum provides a single error type for all operations,
32/// making error handling consistent and ergonomic for users.
