So type Rec = &'static [Rec] is not allowed. The size of a recursive type must be finite; in other words the recursive fields of the type must be pointer types. An example of ...

WebJul 1, 2024 · The nonnegative integers can be understood as a recursive data type. Definition 6.3. 1 The set, \mathbb {N}, is a data type defined recursively as: 0 ∈ N. If n ∈ N, then the successor, n + 1, of n is in N. The point here is to make it clear that ordinary induction is simply the special case of structural induction on the recursive Definition 6.3.1.

WebNov 22, 2015 · 1 Answer Sorted by: 6 In usual math notation, Zero is 0 and Succ is 1 +. So: add m Zero = m Is saying m + 0 = m, and: add m (Succ n) = Succ (add m n) Is saying m + (1 + n) = 1 + (m + n). So at every recursive call, the second argument to + decreases by 1, down to the base case of 0.
