(1) (since C++26)
template < class Alloc, class Value >

(2) (since C++26)
1) This deduction guide is provided for std::indirect to allow deduction from a single value.
2) This deduction guide is provided for std::indirect to allow deduction from an allocator whose value type is different from Value .
