Crate rust2fun

A library for functional programming in Rust

Modules

applicative

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

apply

Apply.

combinator

Combinators

contravariant

Contravariant functors.

flatmap

FlatMap.

functor

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

higher

Implementation of Higher Kinded Types for Rust.

invariant

Invariant functors.

monad

Monad.

prelude

Convenience re-export of common members of the library.

semigroupal

Semigroupal.

Macros

apply_iter

Macro to implement Apply for types with Iterator support.

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.

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.

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 [Contravariant].

invariant_functor

Macro to implement Invariant for types implementing Functor.

pipe

Pipe functions.

semigroupal_iter

Macro to implement Semigroupal for types with Iterator support.
