Functions

func CmdCallFor 

func CmdCallFor(cmd Cmd) proto.Message

CmdCallFor returns the proto message type for the call result of cmd.

func ForeachCmd 

func ForeachCmd(ctx context.Context, cmds []Cmd, onlyTerminated bool, cb func(context.Context, CmdID, Cmd) error) error

ForeachCmd calls the callback cb for each command in cmds. If cb returns an error (excluding Break) then the iteration will stop and the error will be returned. If cb returns Break then the iteration will stop and nil will be returned. ForeachCmd creates a non-cancellable sub-context to reduce cancellation complexity in the callback function. If cb panics, the error will be annotated with the panicing command index and command. onlyTerminated: skip commands that were not terminated as capture time
