What is the error interface in Go?

  • Err
  • Error
  • ErrorInterface
  • Errorable
The error interface in Go is represented by the built-in error interface. This interface defines a single method called Error() string, which returns a string representation of the error. Any custom error type that implements this method is considered to satisfy the error interface. This allows Go programs to handle errors uniformly, regardless of their specific error type, by relying on the common Error() method.
