synopsis: Rose trees with cached and accumulating monoidal annotations
description:
Rose (n-ary) trees with both upwards- (/i.e./
cached) and downwards-traveling (/i.e./
accumulating) monoidal annotations. This is used
as the core data structure underlying
the @diagrams@ framework
(<http://projects.haskell.org/diagrams>), but
potentially has other applications as well.
.
Abstractly, a DUALTree is a rose (n-ary) tree
with data (of type @l@) at leaves, data (of type
@a@) at internal nodes, and two types of monoidal
annotations, one (of type @u@) travelling \"up\"
the tree and one (of type @d@) traveling
\"down\".
.
See "Data.Tree.DUAL" for full documentation.
"Data.Tree.DUAL" provides a public API which
should suffice for most purposes.
"Data.Tree.DUAL.Internal" exports more of the
internal implementation---use it at your own
risk.
