Functions

func AwaitWaitGroup

func AwaitWaitGroup(wg *sync.WaitGroup, timeout time.Duration) bool

AwaitWaitGroup calls Wait on the given wait Returns true if the Wait() call succeeded before the timeout Returns false if the Wait() did not return before the timeout

func CommandToString

func CommandToString(d *commandpb.Command) string

CommandToString convert Command to string

func HistoryEventToString

func HistoryEventToString(e *historypb.HistoryEvent) string

HistoryEventToString convert HistoryEvent to string

func IsInterfaceNil

func IsInterfaceNil(i interface{}) bool

IsInterfaceNil check if interface is nil

func MergeDictoRight

func MergeDictoRight(src map[string]string, dest map[string]string)

MergeDictoRight copies the contents of src to dest

func MergeDicts

func MergeDicts(dic1 map[string]string, dic2 map[string]string) (resultDict map[string]string)

MergeDicts creates a union of the two dicts

Types

type OnceCell

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

A OnceCell attempts to match the semantics of Rust's `OnceCell`, but only stores strings, since that's what's needed at the moment. Could be changed to use interface{} to be generic.

func LazyOnceCell

func LazyOnceCell(fetcher fetcher) OnceCell

LazyOnceCell creates a cell with no initial value, the provided function will be called once and only once the first time OnceCell.Get is called

func PopulatedOnceCell

func PopulatedOnceCell(value string) OnceCell

PopulatedOnceCell creates an already-initialized cell

func (*OnceCell) Get

func (oc *OnceCell) Get() string

Get fetches the value in the cell, calling the fetcher function if it has not yet been called
