Constructs a monotonic_buffer_resource. The constructors not taking an upstream memory resource pointer use the return value of std::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
