Module fat

We define a type FatNode, named for analogy with a “fat pointer”.

We define a trait FatExt, an extension trait for HugrView. It provides methods that return FatNodes rather than Nodes.

Structs

• FatNode
  A Fat Node is a Node along with a reference to the HugrView whence it originates. It carries a type OT, the OpType of that node. OT may be general, i.e. exactly OpType, or specifec, e.g. FuncDefn.

Traits

• FatExt
  An extension trait for HugrView which provides methods that delegate to HugrView and then return the result in FatNode form. See for example FatExt::fat_io.
