7//! The `nydus-error` crate provides commonly used error handling utilities and helpers for Nydus,
8//! including:
9//! - [`fn make_error()`](error.fn.make_error.html): display error messages with line number,
10//!   file path and optional backtrace.
11//! - Macros for commonly used error code, such as `einval!()`, `enosys!()` etc.
12//! - [`struct ErrorHolder`](logger.struct.ErrorHolder.html): a circular ring buffer to hold latest
13//!   error messages.
