Implementation for Nonempty_list.t.
A Nonempty_list.t is a list that contains at least one element. Therefore, the head and tails functions are total and safe.
module Functor : Preface_specs.FUNCTOR with type 'a t = 'a tmodule Alt : Preface_specs.ALT with type 'a t = 'a tNonempty_list.t implements Preface_specs.APPLICATIVE and introduces an interface to define Preface_specs.TRAVERSABLE using Nonempty_list as an iterable structure.
module Applicative :
Preface_specs.Traversable.API_OVER_APPLICATIVE with type 'a t = 'a tmodule Selective : Preface_specs.SELECTIVE with type 'a t = 'a tNonempty_list.t implements Preface_specs.MONAD and introduces an interface to define Preface_specs.TRAVERSABLE using Nonempty_list as an iterable structure.
module Monad : Preface_specs.Traversable.API_OVER_MONAD with type 'a t = 'a tmodule Comonad : Preface_specs.COMONAD with type 'a t = 'a tmodule Foldable : Preface_specs.FOLDABLE with type 'a t = 'a tBy setting the inner type type of Nonempty_list.t it is possible to get implementations for abstractions twithout type parameter.
module Semigroup
(T : Preface_specs.Types.T0) :
Preface_specs.SEMIGROUP with type t = T.t tAdditional functions to facilitate practical work with Nonempty_list.t.
val pure : 'a -> 'a tCreate a value from 'a to 'a t.
val create : 'a -> 'a tcreate x create a new non-empty list with x.
val from_list : 'a list -> 'a t optionCreates a non-empty list from a regular list.
val to_list : 'a t -> 'a listConvert non-empty list to a regular list.
val hd : 'a t -> 'aReturns the head of a non-empty list.
val length : 'a t -> intReturns the length of a non-empty list.
rev_append a b is a tail-recursive version of append (rev a) b.
val iter : ('a -> unit) -> 'a t -> unitList.iter for non-empty list.
val iteri : (int -> 'a -> unit) -> 'a t -> unitList.iteri for non-empty list.
val reduce : ('a -> 'a -> 'a) -> 'a t -> 'areduce f xs reduce all value of xs into one.
val fold_left : ('a -> 'b -> 'a) -> 'a -> 'b t -> 'aList.fold_left for non-empty list.
val fold_right : ('a -> 'b -> 'b) -> 'a t -> 'b -> 'bList.fold_right for non-empty list.
val pp : (Format.formatter -> 'a -> unit) -> Format.formatter -> 'a t -> unitFormatter for pretty-printing for Nonempty_list.t.
