multierr

multierr allows combining one or more Go errors together.

Features

• Idiomatic:
  multierr follows best practices in Go, and keeps your code idiomatic.
  • It keeps the underlying error type hidden,
    allowing you to deal in error values exclusively.
  • It provides APIs to safely append into an error from a defer statement.
• Performant:
  multierr is optimized for performance:
  • It avoids allocations where possible.
  • It utilizes slice resizing semantics to optimize common cases
    like appending into the same error object from a loop.
• Interoperable:
  multierr interoperates with the Go standard library's error APIs seamlessly:
  • The errors.Is and errors.As functions just work.
• Lightweight:
  multierr comes with virtually no dependencies.
