Types ¶
type FinalizeFunc ¶
type FinalizeFunc func()
FinalizeFunc is a function returned by a successful function call, which finalizes the initial function call. A call that returns an error should return a nil FinalizeFunc. When a call returns both a RevertFunc and a FinalizeFunc, at most one may be called. The side effects of the FinalizeFunc are not reverted by the RevertFunc.
type FinalizeList ¶
type FinalizeList struct {
// contains filtered or unexported fields
}
FinalizeList is a list of FinalizeFuncs to be executed in the same order they were appended.
func (*FinalizeList) Append ¶
func (f *FinalizeList) Append(finalizeFunc FinalizeFunc)
Append appends the given FinalizeFunc at the end of this list. If the function is nil, it is ignored.
func (*FinalizeList) Finalize ¶
func (f *FinalizeList) Finalize()
Finalize executes all the FinalizeFuncs in the given list in the same order they were pushed.
type RevertFunc ¶
type RevertFunc func() error
RevertFunc is a function returned by a successful function call, which reverts the side-effects of the initial function call. A call that returns an error should return a nil RevertFunc.
type RevertStack ¶
type RevertStack struct {
// contains filtered or unexported fields
}
RevertStack is a stack of RevertFuncs to be executed in the reverse order they were pushed.
func (*RevertStack) Extend ¶
func (s *RevertStack) Extend(t RevertStack)
Extend extends the revert stack by the given stack.
func (*RevertStack) Push ¶
func (s *RevertStack) Push(revertFunc RevertFunc)
Push pushes the given RevertFunc on top of this stack. If the function is nil, it is ignored.
func (*RevertStack) Revert ¶
func (s *RevertStack) Revert() error
Revert executes all the RevertFuncs in the given stack in the reverse order they were pushed.
