Constructs a monotonic_buffer_resource
. The constructors not taking a upstream memory resource pointer uses 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
