Iterators

The new iter package provides the basic definitions for working with user-defined iterators.

The slices package adds several functions that work with iterators:

  • All returns an iterator over slice indexes and values.
  • Values returns an iterator over slice elements.
  • Backward returns an iterator that loops over a slice backward.
  • Collect collects values from an iterator into a new slice.
  • AppendSeq appends values from an iterator to an existing slice.
  • Sorted collects values from an iterator into a new slice, and then sorts the slice.
  • SortedFunc is like Sorted but with a comparison function.
  • SortedStableFunc is like SortFunc but uses a stable sort algorithm.
