structure Lean.Elab.Tactic.Do.JumpSiteInfo : Type

• numJoinParams : Nat

  Number of join point arguments.

• altIdx : Nat

  Index of the match alternative.

• altParams : Array Expr

  Parameter FVars of the match alternative.

• altLCtxIdx : Nat

  The size of the local context in the alternative after the match has been split and all splitter parameters have been introduced. This is so that we can construct the Σ Lᵢ part of the hyps field.

• hyps : MVarId

  MVar to be filled with the stateful hypotheses of the match arm. This should include bindings from the local context Lᵢ of the call site and is of the form (x,y,z ∈ Lᵢ) Σ Lᵢ, ⌜x = a ∧ y = b ∧ z = c⌝ ∧ Hᵢ, where ..., Lᵢ ⊢ Hᵢ ⊢ₛ wp[jp x y z] Q is the call site. The Σ Lᵢ is short for something like let x := ...; ∃ y (h : y = ...), ∃ z, ∃ (h₂ : p).

• joinPrf : Expr

  The proof that jump sites should use to discharge Hᵢ ⊢ₛ wp[jp a b c] Q.
