Constructs a monotonic_buffer_resource. The constructors not taking an upstream memory resource pointer uses the return value of std::experimental::pmr::get_default_resource() as the upstream memory resource.
1-2) Sets the current buffer to null and the next buffer size to an implementation-defined size.
3-4) Sets the current buffer to null and the next buffer size to a size no smaller than initial_size.
5-6) Sets the current buffer to buffer and the next buffer size to buffer_size (but not less than 1). Then increase the next buffer size by an implementation-defined growth factor (which does not have to be integral).
7) Copy constructor is deleted.
Parameters
| upstream | - | the upstream memory resource to use; must point to a valid memory resource |
| initial_size | - | the minimum size of the first buffer to allocate; must be greater than zero |
| buffer | - | the initial buffer to use |
| buffer_size | - | the size of the initial buffer; cannot be greater than the number of bytes in buffer |
