std::get(std::span)
From cppreference.com
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[].
Parameters
s | - | span whose contents to extract |
Return value
A reference to the Ith
element of s
.
Complexity
Constant.
