Functions ¶
func Pull ¶
Pull converts the “push-style” iterator sequence seq into a “pull-style” iterator accessed by the two functions next and stop.
Next returns the next value in the sequence and a boolean indicating whether the value is valid. When the sequence is over, next returns the zero V and false. It is valid to call next after reaching the end of the sequence or after calling stop. These calls will continue to return the zero V and false.
Stop ends the iteration. It must be called when the caller is no longer interested in next values and next has not yet signaled that the sequence is over (with a false boolean return). It is valid to call stop multiple times and when next has already returned false.
It is an error to call next or stop from multiple goroutines simultaneously.
func Pull2 ¶
Pull2 converts the “push-style” iterator sequence seq into a “pull-style” iterator accessed by the two functions next and stop.
Next returns the next pair in the sequence and a boolean indicating whether the pair is valid. When the sequence is over, next returns a pair of zero values and false. It is valid to call next after reaching the end of the sequence or after calling stop. These calls will continue to return a pair of zero values and false.
Stop ends the iteration. It must be called when the caller is no longer interested in next values and next has not yet signaled that the sequence is over (with a false boolean return). It is valid to call stop multiple times and when next has already returned false.
It is an error to call next or stop from multiple goroutines simultaneously.
