func RunTasks ¶

func RunTasks(ctx context.Context, tasks ...func(context.Context) error) error

RunTasks executes all of the provided functions concurrently and waits for them all to complete. If a function returns an error, all other functions are canceled (i.e. the context they are passed is canceled) and the error is returned. If all functions finish to completion successfully, RunTasks returns nil. If the context passed to RunTasks is canceled then each function is canceled and RunTasks returns ctx.Err(). Tasks passed to RunTasks MUST support cancelation via the provided context for RunTasks to work properly.
