Crate rust2fun

A library for functional programming in Rust

Modules

and_then

AndThen.

ap_n

ApN.

applicative

Applicative functor. Allows application of a function in an Applicative context to a value in an Applicative context.

apply

Apply.

bifunctor

Bifunctor is a type constructor that takes two type arguments and is a functor in both arguments.

combinator

Combinators

contravariant

Contravariant functors.

data

Data types.

flatmap

FlatMap.

functor

Functor. The name is short for “covariant functor”.

higher

Implementation of Higher Kinded Types for Rust.

invariant

Invariant functors.

map_n

MapN.

monad

Monad.

monoid

Monoid.

prelude

Convenience re-export of common members of the library.

pure

Pure.

semigroup

Semigroup.

semigroupal

Semigroupal.

Macros

and_then_flat_map

Macro to implement AndThen for types implementing a FlatMap::flat_map.

apply_iter

Macro to implement Apply for types with Iterator support.

bind

Bind macro. Allows for a more natural syntax for monadic composition. It is similar to the do notation in Haskell or the for notation in Scala.

compose

Compose functions.

constant

The constant with no arguments constant(x) = () -> x.

constant1

The constant function constant1(x) = _ -> x also known as K (Kestrel) combinator.

constant2

The constant function with two arguments constant2(x) = (_, _) -> x.

constant3

The constant function with 3 arguments constant3(x) = (_, _, _) -> x.

constant4

The constant function with 4 arguments constant4(x) = (_, _, _, _) -> x.

constant5

The constant function with 5 arguments constant5(x) = (_, _, _, _, _) -> x.

constant6

The constant function with 6 arguments constant6(x) = (_, _, _, _, _, _) -> x.

constant7

The constant function with 7 arguments constant7(x) = (_, _, _, _, _, _, _) -> x.

constant8

The constant function with 8 arguments constant8(x) = (_, _, _, _, _, _, _, _) -> x.

constant9

The constant function with 9 arguments constant9(x) = (_, _, _, _, _, _, _, _, _) -> x.

constant10

The constant function with 10 arguments constant10(x) = (_, _, _, _, _, _, _, _, _, _) -> x.

constant11

The constant function with 11 arguments constant11(x) = (_, _, _, _, _, _, _, _, _, _, _) -> x.

constant12

The constant function with 12 arguments constant12(x) = (_, _, _, _, _, _, _, _, _, _, _, _) -> x.

curry2

Curry a function of two arguments. The first argument is applied to the function. The second argument is returned as a closure. The returned closure can be applied to the second argument. The result is the same as applying the function to both arguments.

curry3

Curry a function of 3 arguments.

curry4

Curry a function of 4 arguments.

curry5

Curry a function of 5 arguments.

curry6

Curry a function of 6 arguments.

curry7

Curry a function of 7 arguments.

curry8

Curry a function of 8 arguments.

curry9

Curry a function of 9 arguments.

curry10

Curry a function of 10 arguments.

curry11

Curry a function of 11 arguments.

curry12

Curry a function of 12 arguments.

flatmap_iter

Macro to implement FlatMap for types with Iterator support.

flip

Flip arguments of a function flip(f)(x, y) = f(y, x) also known as C (Cardinal) combinator.

functor_iter

Macro to implement Functor for types with Iterator support.

higher

Macro implementing Higher for a given type of kind * -> *.

invariant_contravariant

Macro to implement Invariant for types implementing a contravariant Functor.

invariant_functor

Macro to implement Invariant for types implementing Functor.

ne_vec

Creates a NEVec containing the arguments.

pipe

Pipe functions.

semigroup_append

Macro to implement Semigroup for types with append method.

semigroup_extend

Macro to implement Semigroup for types with extend method.

semigroupal_iter

Macro to implement Semigroupal for types with Iterator support.
