Types

type CleanJob

type CleanJob func() error

type CleanStack

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

CleanStack is a basic LIFO stack that resizes as needed.

func NewCleanStack

func NewCleanStack() *CleanStack

NewCleanStack returns a new stack. It's used to push jobs into it that need to be executed in order, like unmounting disks or removing dirs, and it will run those jobs in the order they were pushed into it to maintain order So you can create a dir, push its removal into the stack, mount something into that dir and push its unmounting into the stack and when cleanup is triggered it will first unmount and then remove the dir Usually its setup inside a function with a defer immediately so it auto cleans if you return from anywhere in the function That way you don't need to track on each return what needs to be cleaned and whatnot cleanup := utils.NewCleanStack() defer func() { err = cleanup.Cleanup(err) }()

func (*CleanStack) Cleanup

func (clean *CleanStack) Cleanup(err error) error

Cleanup runs the whole cleanup stack. In case of error it runs all jobs and returns the first error occurrence.

func (*CleanStack) Pop

func (clean *CleanStack) Pop() CleanJob

Pop removes and returns a node from the stack in last to first order.

func (*CleanStack) Push

func (clean *CleanStack) Push(job CleanJob)

Push adds a node to the stack

type KeyNotFoundErr

type KeyNotFoundErr struct {
	Err error
}

func (KeyNotFoundErr) Error

func (err KeyNotFoundErr) Error() string
