Theorem: UInt.maskTable_size (Algdata/Classes/UInt.lean)

State before:
α : Type
inst✝¹ : (n : Nat) → OfNat α n
inst✝ : UInt α
⊢ Array.size maskTable = Nat.log2RU (length α)
Tactic:
unfold maskTable
State after:
α : Type
inst✝¹ : (n : Nat) → OfNat α n
inst✝ : UInt α
⊢ Array.size (Array.ofFn fun i => bitmask (OfNat.ofNat ↑i)) = Nat.log2RU (length α)
