Kinder | Algebraic structure and emulation of higher kinded types | Functional Programming library

Kinder is a Rust library typically used in Programming Style, Functional Programming applications. Kinder has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Kinder provides some tools and traits that functional programmers use daily. Updates: Moved all macros to lift.rs for ease of use. The lift module defines the Higher struct which allows creation of higher kinded types. It also exports the macro lift! which implements Higher for types of kind * -> *. Implements SemiGroup for std::collections as well as String. Provides a method add which takes two items of the same type and returns an element of the same type. Implements Monoid for std::collections as well as String. Provides and id method for SemiGroups such that x.add(T::id()) = x. Implements Foldable for std::collections. Provides a method foldr which takes a starting value and a function and folds the Foldable using the function. See examples for more information. Implements Functor for std::collections and exports a macro functorize! which makes a functor out of any lifted type which implements iter. Implements Applicative for std::collections which supplies two methods. Raise takes a T and raises it to be an A , i.e Vec::lift(1) = vec!(1). Apply takes an applicative, and a lifted functions and applies it, i.e vec!(1,2).apply(vec!(|x| x+1, |x| x*x)) = vec!(2, 4). Implements Monad for std::collections. Monads have two functions, lift (normally return but return is reserved in Rust), and bind. Lift takes and element and "lifts" it into the Monad, for example Option::lift(2) = Some(2). Bind is similar to fmap except the mapping function has type: A -> M i.e i32 -> Option. Bind is often implemented using flat_map.
