Module `Relude_StateT.State`

type t('a, 's) = WithMonad(Relude_Identity.Monad).t('a, 's) = | StateT('s => Relude_Identity.Monad.t(('a, 's))) ;: StateT represents an effectful function from a state value of type 's to a result value 'a and a next state of type 's. This version of StateT has 'a on the left for consistency with other Reason types like Result/IO/Validation/etc.
