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.ExprPtr : Type

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

• expr : Expr
