#include <userver/utils/fixed_array.hpp>

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");
