opaque Lean.Expr.foldConsts {α : Type} (e : Lean.Expr) (init : α) (f : Lean.Name → α → α) : α

Apply f to every constant occurring in e once.

def Lean.Expr.getUsedConstants (e : Lean.Expr) : Array Lean.Name

Equations

• e.getUsedConstants = e.foldConsts #[] fun (c : Lean.Name) (cs : Array Lean.Name) => cs.push c

def Lean.Expr.getUsedConstantsAsSet (e : Lean.Expr) : Lean.NameSet

Like Expr.getUsedConstants, but produce a NameSet.

Equations

• e.getUsedConstantsAsSet = e.foldConsts ∅ fun (c : Lean.Name) (cs : Lean.NameSet) => cs.insert c

def Lean.ConstantInfo.getUsedConstantsAsSet (c : Lean.ConstantInfo) : Lean.NameSet

Return all names appearing in the type or value of a ConstantInfo.
