template< std::size_t I, class T, std::size_t N > constexpr T& get( std::span<T,N> s ) noexcept; | (since C++20) |
Obtains a reference to the Ith element of the span s.
The span must have static extent (i.e., N != std::dynamic_extent) and I must be an integer value in range [0, N). This is enforced at compile time as opposed to operator[].
| s | - | span whose contents to extract |
A reference to the Ith element of s.
Constant.
| accesses an element of the sequence (public member function) |
|
| tuple accesses specified element (function template) |
|
|
(C++11) | accesses an element of a pair (function template) |
|
(C++17) | reads the value of the variant given the index or the type (if the type is unique), throws on error (function template) |
