callback

type Callback ¶

type Callback[T any] interface {
	// Complete is invoked when the operation completes successfully with the result 't' of type T.
	Complete(t T)

	// CompleteError is invoked when the operation fails, providing an error 'err' indicating the failure reason.
	CompleteError(err error)
}

Callback defines an interface for handling the completion of an asynchronous operation. It allows the caller to notify the system when an operation has completed successfully or when it has failed with an error. The interface provides two methods for handling both success and error cases.

The generic type T represents the result type of the operation, which can vary depending on the specific use case.

Methods:

• Complete(t T): This method is called when the asynchronous operation completes successfully. It accepts a result of type T, which is the outcome of the operation.

• CompleteError(err error): This method is called when the asynchronous operation fails. It accepts an error, which indicates the reason for the failure.

func NewOnce[T any](onComplete func(t T), onError func(err error)) Callback[T]

type Once ¶

type Once[T any] struct {
	OnComplete      func(t T)       // Callback function called on successful completion
	OnCompleteError func(err error) // Callback function called when an error occurs
	// contains filtered or unexported fields
}

func (c *Once[T]) Complete(t T)

func (c *Once[T]) CompleteError(err error)
