Functions

func Len

func Len(iter Iterator) int

Len consumes the iterator and returns the number of elements found.

IMPORTANT: this method consumes the iterator, so it should not be used after Len() returns.

Types

type Iterator

type Iterator interface {
	// Next returns the next element or nil if there are none left.
	Next() any
}

Iterator represents an object that can iterate over a set of values one at a time.
