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
