Agda-2.3.0: A dependently typed functional programming language and proof assistant



Detect if a datatype could be represented as a primitive integer. If it has one constructor with no arguments and one with a recursive argument this is true. This is done using IrrFilters which filter out forced arguments, so for example Fin becomes primitive.



getNatish :: Compile TCM [(ForcedArgs, [QName])]Source

Get a list of all the datatypes that look like nats. The [QName] is on the form [zeroConstr, sucConstr]

nrRel :: ForcedArgs -> IntegerSource

Count the number of relevant arguments

isRec :: Int -> Type -> QName -> BoolSource

Check if argument n is recursive
