Description

Trait composition.

Modules

Classes
struct	meta::bind_back< F, Us >
	A Callable that partially applies the Callable F by binding the arguments Us to the back of F. More...
struct	meta::bind_front< F, Ts >
	A Callable that partially applies the Callable F by binding the arguments Ts to the front of F. More...
struct	meta::compose< Fs >
	Compose the Callables Fs in the parameter pack Ts. More...
struct	meta::flip< F >
	A Callable that reverses the order of the first two arguments. More...
struct	meta::quote< C >
	Turn a class template or alias template C into a Callable. More...
struct	meta::quote_i< T, C >
	Turn a class template or alias template C taking literals of type T into a Callable. More...

Typedefs
template<typename F , typename Q = quote<list>>
using	meta::curry = compose< F, Q >
	A Callable that takes a bunch of arguments, bundles them into a type list, and then calls the Callable F with the type list Q.
template<typename... Fs>
using	meta::on = detail::on_< Fs... >
	Use as on<F, Gs...>. Creates an Callable that applies Callable F to the result of applying Callable compose<Gs...> to all the arguments.
template<template< typename... > class C>
using	meta::quote_trait = compose< quote< _t >, quote< C >>
	Turn a trait template C into a Callable. More...
template<typename T , template< T... > class C>
using	meta::quote_trait_i = compose< quote< _t >, quote_i< T, C >>
	Turn a trait C taking literals of type T into a Callable. More...
template<typename F >
using	meta::uncurry = bind_front< quote< apply >, F >
	A Callable that takes a type list, unpacks the types, and then calls the Callable F with the types.
