[section Header <boost/core/static_assert.hpp>]
|
|
|
|
The header `<boost/core/static_assert.hpp>` defines
|
|
the macro `BOOST_CORE_STATIC_ASSERT(expr)`, which
|
|
expands to `static_assert(expr, #expr)` under C++11
|
|
or later, or to a suitable emulation under C++03.
|
|
|
|
The same functionality is provided by `BOOST_STATIC_ASSERT`
|
|
defined in `<boost/static_assert.hpp>`, and the macro
|
|
is duplicated here for libraries that already depend
|
|
on Core and would like to remove the dependency on
|
|
StaticAssert.
|
|

|
[section Synopsis]
|
|
|
|

|
|
#define BOOST_CORE_STATIC_ASSERT(expr) static_assert(expr, #expr)
