value::get

`value::get_array`

Return a reference to the underlying array, without checking.

array&
get_array() & noexcept; (1)

array&&
get_array() && noexcept; (2)

array const&
get_array() const& noexcept; (3)

This is the fastest way to access the underlying representation when the kind is known in advance.

this->is_array()

Constant.

No-throw guarantee.
