filter f m returns the RBMap consisting of all "key/val"-pairs in m where f key val returns true.

Equations

• Lean.RBMap.filter f m = Lean.RBMap.fold (fun (r : Lean.RBMap α β cmp) (k : α) (v : β) => if f k v = true then r.insert k v else r) ∅ m

def Lean.RBMap.filterMap {α : Type u} {β : Type v} {cmp : α → α → Ordering} {γ : Type u_1} (f : α → β → Option γ) (m : RBMap α β cmp) : RBMap α γ cmp

filterMap f m filters an RBMap and simultaneously modifies the filtered values.

It takes a function f : α → β → Option γ and applies f k v to the value with key k. The resulting entries with non-none value are collected to form the output RBMap.

Equations

• Lean.RBMap.filterMap f m = Lean.RBMap.fold (fun (r : Lean.RBMap α γ cmp) (k : α) (v : β) => match f k v with | none => r | some b => r.insert k b) ∅ m

def Lean.rbmapOf {α : Type u} {β : Type v} (l : List (α × β)) (cmp : α → α → Ordering) : RBMap α β cmp

Equations

• Lean.rbmapOf l cmp = Lean.RBMap.fromList l cmp
