Convenience alias template for naming a
ranges::tagged
wrapping a
std::tuple
.
A
TaggedType
is a function type
S(T)
, where
S
is a
TagSpecifier
and
T
is the type of the element.
tagged_tuple < S1 ( T1 ) , ..., SN ( TN ) > is an alias for ranges:: tagged < std:: tuple < T1, ..., TN > , S1, ..., SN > .
Notes
Because a function type is used to "glue" the tag specifier and the corresponding element type together, the usual parameter type adjustments apply. In particular, top-level cv-qualifiers are removed and array types are adjusted to pointers: tagged_tuple < tag:: in ( const int * const ) , tag:: out ( int [ ] ) > is ranges:: tagged < std:: tuple < const int * , int * > , tag:: in , tag:: out > .
