FuncLeaf constructs a Leaf from an open function.

IterateAll reads iter until EOF.

IterateFull reads the full len(dst) nodes from Iterator.

MapIterator returns an Iterator that applies fn to each T yielded by iter.

NewConcatIterator returns the elements of the given iterators in order, reading each until EOF.

NewDirInfo constructs FileInfo for a directory.

NewIterator returns an iterator that yields the given nodes.

NewLazyIterator uses the given make function upon the first call to Next to make the nodes that it yields.

NewParent returns a Parent whose children are defined by gen.

NewRegInfo constructs FileInfo for a regular file.
