std::get(std::span) (3) - Linux Man Pages

std::get(std::span): std::get(std::span)

NAME

std::get(std::span) - std::get(std::span)

Synopsis


template< std::size_t I, class T, std::size_t N > (since C++20)
constexpr T& get( std::span<T,N> s ) noexcept;


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[].

Parameters


s - span whose contents to extract

Return value


A reference to the Ith element of s.

Complexity


Constant.
