multierr is a lightweight Go library for combining one or more errors into a single error value. It is idiomatic, performant, and interoperates seamlessly with the standard library's errors.Is and errors.As APIs.

Use cases

  • combine multiple errors from a loop into one
  • append errors safely from defer statements
  • aggregate errors from parallel goroutines
  • return all validation errors at once instead of only the first
  • work with multiple errors using errors.Is and errors.As

When to choose

  • you need to collect and report multiple errors together in Go
  • you want a dependency-free, stable error-combining library
  • you need compatibility with Go 1.20+ errors.Is/errors.As semantics

When to avoid

  • you are on Go 1.20+ and only need basic multi-error wrapping via the standard errors.Join
  • you need rich error formatting or stack traces, which other libraries provide
