WebOct 19, 2016 · 2. SmallVector is almost same as std::vector except it keeps its data inside a large array. Similar to std::array, its size can not get bigger than the SIZE parameter. However, unlike std::array it may hold less than SIZE elements. I try to made it constexpr, but it is not really possible, because push_back need to throw an exception in case of ...

WebAug 30, 2013 · The Container library of Boost v1.58 (april 2015) has the experimental small_vector container:. small_vector is a vector-like container optimized for the case when it contains few elements. It contains some preallocated elements in-place, which allows it to avoid the use of dynamic storage allocation when the actual number of elements is below …class llvm::SmallVector< T, N >. This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small. It contains some number of elements in-place, which allows it to avoid heap allocation when the actual number of elements is below that threshold.
