Types

type CallStack 

type CallStack struct {
	sync.Mutex
	// contains filtered or unexported fields
}

func NewCallStack 

func NewCallStack() *CallStack

NewCallStack creates a new CallStack

func (*CallStack) Add 

func (c *CallStack) Add(fn CallableFn)

Add Adds a callback

func (*CallStack) IsCalling 

func (c *CallStack) IsCalling() bool

IsCalling returns true if in call loop

func (*CallStack) Run 

func (c *CallStack) Run(abortOnError bool) error

Run executes the callback functions in the CallStack in reverse order. If abortOnError is true and any of the callback functions return an error, the execution stops and returns that error. If abortOnError is false, all callback functions are executed, regardless of errors, and the errors returned by the callbacks are combined with errors.Join. The callbacks registered at the time of the call are executed without holding the CallStack lock, so a callback may safely call Add; callbacks added during execution are not executed by the current call. The calling flag is set to 1 during the execution and reset to 0 after execution. If the CallStack is empty, Run returns nil.

func (*CallStack) RunLinear 

func (c *CallStack) RunLinear(abortOnError bool) error

RunLinear executes each callback function in the call stack linearly. Error handling and locking behave as in Run.

type CallableFn 

type CallableFn func() error

CallableFn CallStack callable function
