def Lean.Elab.Structural.withFunTypes {α : Type} (values : Array Expr) (k : Array Expr → M α) : M α

Turns fun a b => x into let funType := fun a b => α (where x : α). The continuation is the called with all funTypes corresponding to the values.

def Lean.Elab.Structural.mkIndPredBRecOnMotive (recArgInfo : RecArgInfo) (value funType : Expr) : M Expr

Calculates the .brecOn motive corresponding to one structural recursive function. The value is the function with (only) the fixed parameters moved into the context.

def Lean.Elab.Structural.mkIndPredBRecOnF (recArgInfos : Array RecArgInfo) (positions : Positions) (recArgInfo : RecArgInfo) (value FType : Expr) (params : Array Expr) : M Expr

Calculates the .brecOn functional argument corresponding to one structural recursive function. The value is the function with (only) the fixed parameters moved into the context, The FType is the expected type of the argument. The recArgInfos is used to transform the body of the function to replace recursive calls with uses of the below induction hypothesis.
