Types ¶

type Composite ¶

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

func (*Composite) Add ¶

func (c *Composite) Add(f func(context.Context) error)

Add adds a cleanup to be called.

func (*Composite) Call ¶

func (c *Composite) Call(ctx context.Context) error

Call calls all cleanups in reverse order and returns an error combining all non-nil errors.

func (*Composite) Release ¶

func (c *Composite) Release() func(context.Context) error

Release removes all cleanups, turning Call into a no-op. Caller still can call the cleanups by calling the returned function which is equivalent to calling the Call before Release was called.
