structure Lean.Meta.Sym.Simp.Theorem : Type

A simplification theorem for the structural simplifier.

Contains both the theorem expression and a precomputed pattern for efficient unification during rewriting.

• expr : Expr

  The theorem expression, typically Expr.const declName for a named theorem.

• pattern : Pattern

  Precomputed pattern extracted from the theorem's type for efficient matching.

• rhs : Expr

  Right-hand side of the equation.
