def Lean.Meta.mkSizeOfFn (recName : Lean.Name) (declName : Lean.Name) : Lean.MetaM Unit

Create a "sizeOf" function with name declName using the recursor recName.

def Lean.Meta.mkSizeOfFns (typeName : Lean.Name) : Lean.MetaM (Array Lean.Name × Lean.NameMap Lean.Name)

Create sizeOf functions for all inductive datatypes in the mutual inductive declaration containing typeName The resulting array contains the generated functions names. The NameMap maps recursor names into the generated function names. There is a function for each element of the mutual inductive declaration, and for auxiliary recursors for nested inductive types.
