inductive Lean.Meta.Grind.Origin : Type

• decl (declName : Name) : Origin

  A global declaration in the environment.

• fvar (fvarId : FVarId) : Origin

  A local hypothesis.

• stx (id : Name) (ref : Syntax) : Origin

  A proof term provided directly to a call to grind where ref is the provided grind argument. The id is a unique identifier for the call.

• other : Origin

instance Lean.Meta.Grind.instInhabitedOrigin : Inhabited Origin

Equations

• Lean.Meta.Grind.instInhabitedOrigin = { default := Lean.Meta.Grind.Origin.decl default }

A unique identifier corresponding to the origin.

Equations

• (Lean.Meta.Grind.Origin.decl a).key = a

structure Lean.Meta.Grind.EMatchTheorem : Type

A theorem for heuristic instantiation based on E-matching.

• levelParams : Array Name

  It stores universe parameter names for universe polymorphic proofs. Recall that it is non-empty only when we elaborate an expression provided by the user. When proof is just a constant, we can use the universe parameter names stored in the declaration.

• proof : Expr
• numParams : Nat
• patterns : List Expr
• symbols : List HeadIndex

  Contains all symbols used in pattterns.

• origin : Origin
