// Lines returns an iterator over the newline-terminated lines in the byte slice s.
// The lines yielded by the iterator include their terminating newlines.
// If s is empty, the iterator yields no lines at all.
// If s does not end in a newline, the final yielded line will not end in a newline.
// It returns a single-use iterator.
func Lines(s []byte) iter.Seq[[]byte] { … }

// explodeSeq returns an iterator over the runes in s.
func explodeSeq(s []byte) iter.Seq[[]byte] { … }

// splitSeq is SplitSeq or SplitAfterSeq, configured by how many
// bytes of sep to include in the results (none or all).
func splitSeq(s, sep []byte, sepSave int) iter.Seq[[]byte] { … }

// SplitSeq returns an iterator over all substrings of s separated by sep.
// The iterator yields the same strings that would be returned by Split(s, sep),
// but without constructing the slice.
// It returns a single-use iterator.
func SplitSeq(s, sep []byte) iter.Seq[[]byte] { … }

// SplitAfterSeq returns an iterator over substrings of s split after each instance of sep.
// The iterator yields the same strings that would be returned by SplitAfter(s, sep),
// but without constructing the slice.
// It returns a single-use iterator.
func SplitAfterSeq(s, sep []byte) iter.Seq[[]byte] { … }

// FieldsSeq returns an iterator over substrings of s split around runs of
// whitespace characters, as defined by unicode.IsSpace.
// The iterator yields the same strings that would be returned by Fields(s),
// but without constructing the slice.
func FieldsSeq(s []byte) iter.Seq[[]byte] { … }

// FieldsFuncSeq returns an iterator over substrings of s split around runs of
// Unicode code points satisfying f(c).
// The iterator yields the same strings that would be returned by FieldsFunc(s),
// but without constructing the slice.
