def Lean.Meta.Grind.isSameExpr (a b : Expr) : Bool

Equations

• Lean.Meta.Grind.isSameExpr a b = Lean.Meta.Grind.isSameExpr.unsafe_impl_3 a b

structure Lean.Meta.Grind.ENodeKey : Type

Key for the ENodeMap and ParentMap map. We use pointer addresses and rely on the fact all internalized expressions have been hash-consed, i.e., we have applied shareCommon.

• expr : Expr

abbrev Lean.Meta.Grind.hashPtrExpr (e : Expr) : UInt64

Equations

• Lean.Meta.Grind.hashPtrExpr e = Lean.Meta.Grind.hashPtrExpr.unsafe_impl_3 e
