Types

type Cleanup

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

Cleanup allows defers to be aborted when cleanup needs to happen conditionally. Usage:

	 cu := cleanup.Make(func() { f.Close() })
	 defer cu.Clean() // failure before release is called will close the file.
	 ...
  cu.Add(func() { f2.Close() })  // Adds another cleanup function
  ...
	 cu.Release() // on success, aborts closing the file.
	 return f

func Make

func Make(f func()) Cleanup

Make creates a new Cleanup object.

func (*Cleanup) Add

func (c *Cleanup) Add(f func())

Add adds a new function to be called on Clean().

func (*Cleanup) Clean

func (c *Cleanup) Clean()

Clean calls all cleanup functions in reverse order.

func (*Cleanup) Release

func (c *Cleanup) Release() func()

Release releases the cleanup from its duties, i.e. cleanup functions are not called after this point. Returns a function that calls all registered functions in case the caller has use for them.
