WebFeb 4, 2024 · Polymorphic Memory Resource (PMR) Strings. I want to finish by touching on an area that probably deserves its own article. C++17 introduced library support for Memory Resources. Memory resources implement memory allocation strategies that can be used by std::pmr::polymorphic_allocator, covered in detail in a previous blog post. WebPolymorphic memory resources allow us to easily implement allocators such as stack, pool, and arena allocators. This can greatly improve performance. For example, if the user knows that a small, dynamically allocated matrix will never exceed some (compile-time known) size, one can use std::pmr::monotonic_buffer_resource to keep the matrix on ...
