go-multierror
A Go package for representing multiple errors as a single error with custom formatting and concurrent error collection.
What is go-multierror?
go-multierror is a Go package that allows developers to represent multiple errors as a single error value. It solves the problem of functions needing to return more than one error by providing aggregation, custom formatting, and concurrent error collection utilities. While Go 1.20 introduced `errors.Join` for basic error combining, go-multierror offers additional features like the `Group` pattern and custom formatting options.
Go developers building applications that require robust error handling, especially those working with concurrent operations or needing to aggregate multiple validation or processing errors.
Developers choose go-multierror for its seamless integration with existing Go error patterns, support for concurrent error collection, and custom formatting capabilities that go beyond the standard library's `errors.Join`.
