WebMar 4, 2024 · pmr is a huge topic, but in short a polymorphic allocator conforms to the rules of a regular allocator from the Standard Library, but it uses memory_resource to manage the memory. The allocator contains a pointer to a memory resource object, and that’s why the compiler can use a virtual method dispatch.

What is the purpose and usage of `memory_resource`?

WebThe memory in the resource is divided into a fixed number of arenas. Each arena consists of a fixed number of bytes. Each arena has the same size. Management of the arenas Initially every arena is empty and they are placed in a set of free arenas. The first allocation request taps an arena and marks it as active. WebThe polymorphic allocator contains a pointer to the interface memory_resource so it can use dynamic dispatch. To change the strategy of working with memory, it is enough to replace the instance memory_resource keeping the type of allocator. This can be done at … the positive impacts of the green revolution https://luniska.com
