Types

type GuardedError

type GuardedError struct {
	// contains filtered or unexported fields
}

GuardedError is a concurrency-safe error wrapper. It is sticky in that the first error won't be overwritten.

func (*GuardedError) Error

func (g *GuardedError) Error() error

Error returns the guarded error.

func (*GuardedError) TrySetError

func (g *GuardedError) TrySetError(err error) bool

TrySetError sets the error, if not already set. Returns true iff the error was set.
