Errors
errors is a Go error handling library and stack trace utility that wraps standard errors with execution call stacks and contextual information. It captures program execution paths at the exact moment an error is initialized, extracting granular file paths, line numbers, and function symbols from raw program counter addresses.
The library maintains parent-child relationships between wrapped errors to allow deep inspection, unwrapping of root causes, and combination of multiple errors into unified structures. It implements standard error interfaces so enhanced error objects can be used interchangeably with normal error returns throughout an application. Additionally, it provides panic recovery capabilities that intercept raw runtime panic output strings, converting them into structured error objects equipped with readable stack traces.
Diagnostic functions print detailed error messages and full stack traces to the console or logs, supporting advanced error formatting with custom messages, formatting strings, and stack depth skipping.
Features
