WebIt will mostly depend on what the compiler manages to figure out from it. If you can't time the operation in a context similar or identical to use (which remains the best way to figure it out), then I would guess a loop with a functor (functor object or lambda) is likely the best bet for the compiler to be able to figure out a cache friendly unroll and a cheap access to the … WebDescription. small_vector is a vector-like container optimized for the case when it contains few elements. It contains some preallocated elements in-place, which can avoid the use of dynamic storage allocation when the actual number of elements is below that preallocated threshold. small_vector is convertible to small_vector ...
