Detailed Description

template<class T>
class utils::FixedArray< T >

A fixed-size array with the size determined at runtime.

The array also allows initializing each of the array elements with the same parameters:

  class NonDefaultConstructible final {
   public:
    explicit NonDefaultConstructible(std::string str) : str_(std::move(str)) {}
 
    std::string GetString() const { return str_; }
 
   private:
    std::string str_;
  };
 
  utils::FixedArray<NonDefaultConstructible> array{42, "The string"};
  ASSERT_EQ(array.size(), 42);
  ASSERT_EQ(array[0].GetString(), "The string");
  ASSERT_EQ(array[14].GetString(), "The string");
  ASSERT_EQ(array[41].GetString(), "The string");
