Detailed Description

template<typename T>
requires std::move_constructible<T>
class siddiqsoft::resource_pool< T >

Implements a resource pool that stores objects of type T. Said objects can be shared_ptr or unique_ptr Client "acquire" and "release" T from this pool. The capacity of this pool should be kept at the same value as std::thread::hardware_concurrency().

Template Parameters

T	The storage element type. Maybe shared_ptr or unique_ptr The only requirement is that the underlying object is move-constructible!
