structure Lean.Elab.Tactic.Do.ProofMode.FocusResult : Type

The result of focusing the context of a goal goal : MGoal on a particular hypothesis. The focused hypothesis is returned as focusHyp : Expr, along with the residual restHyps : Expr and a proof : Expr for the property goal.hyps ⊣⊢ₛ restHyps ∧ focusHyp.

• focusHyp : Expr
• restHyps : Expr
• proof : Expr
