veclib

Veclib is a single-header C++ library for array-like structures (arrays, vectors, slices, lists...).

You can find your basic static array class (Array), dynamic array class (Vector), slice (Slice) and list (LinkedList), but there are also some more complex data structures like LinkedArray or StillVector.

Macros

In veclib we can change the behaviour of certain features by defining some macros:

• VECLIB_ASSERT_NOEXCEPT: disable exceptions and use asserts instead, this also defines VECLIB_NOEXCEPT, a macro that expands to noexcept if this is defined
• VECLIB_NO_OPERATOR_OVERLOADS: don't define extra operator overloads that may clutter code
• VECLIB_EXTRA: define extra methods for some data structures which could be used in niche cases but are not defined by default to avoid unnecessary clutter

Some macros are instead used as internal utilities but are left defined for others to use too:

• VECLIB_NONCONSTRUCTOR_NEW(count, type): Allocate count elements on the heap without calling the constructor of their specified type
• VECLIB_NONDESTRUCTOR_DELETE(data, count): Free count elements on the heap of the type pointed to by the data pointer

Example use:

#include "veclib.hpp"
// Imagine we have this class
class foo;

int main() {
    foo* bar = VECLIB_NONCONSTRUCTOR_NEW(1, foo);
    // Do something with it
    VECLIB_NONDESTRUCTOR_DELETE(bar, 1, foo);
}
