Types

type Initializer

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

Initializer is a chainable initializer. Init/InitOnSystemBus/InitOnSystemBus will accept a initializer, and then pass the successful return value to the next initializer. If error occurs, the rest initializers won't be executed any more. GetError is used to access the error.

func Do

func Do(fn func() error) *Initializer

Do starts the initialization.

func (*Initializer) Do

func (i *Initializer) Do(fn func() error) *Initializer

Do accepts a initializer function, stop other Do if any error occurs.

func (*Initializer) GetError

func (i *Initializer) GetError() error

GetError returns the first error of initializers.
