template<typename T >

void lar::util::details::ResizeToPower2	(	std::vector< T > &	v,
		size_t	min_size
	)

Resizes a vector to a size power of 2, with a minimum size.

---

Parameters

v	the vector to be resized
min_size	the minimal size of the vector

The vector v is resized, any new element is default-initialized. The target size is the smallest power of 2 not smaller than min_size, or 0 if min_size is 0.
