Classes
struct	mysql::ranges::detail::Projection_transform< index_tp >
	Function-like class that projects a tuple-like object to the Nth element. More...

Namespaces
namespace	mysql
namespace	mysql::ranges
namespace	mysql::ranges::detail

Typedefs
template<std::size_t index_tp, std::input_iterator Source_iterator_tp>
using	mysql::ranges::Projection_iterator = Transform_iterator< detail::Projection_transform< index_tp >, Source_iterator_tp >
	Projection iterator adaptor: given an iterator over tuple-like objects, this is an iterator over the Nth component. More...
template<std::size_t index_tp, std::ranges::range Source_tp>
using	mysql::ranges::Projection_view = Transform_view< detail::Projection_transform< index_tp >, Source_tp >
	Projection view: given a range over tuple-like objects, this is a range over the N'th component of those tuples. More...
template<class Value_iterator_t >
using	mysql::ranges::Key_iterator = Projection_iterator< 0, Value_iterator_t >
	Iterator adaptor that extracts the first component from tuple-like value types. More...
template<class Source_t >
using	mysql::ranges::Key_view = Projection_view< 0, Source_t >
	View over the keys of a range of pairs. More...
template<class Value_iterator_t >
using	mysql::ranges::Mapped_iterator = Projection_iterator< 1, Value_iterator_t >
	Iterator adaptor that extracts the second component from tuple-like value types. More...
template<class Source_t >
using	mysql::ranges::Mapped_view = Projection_view< 1, Source_t >
	View over the mapped values in a range of pairs. More...

Functions
template<std::size_t index_t, std::input_iterator Tuple_iterator_t>
auto	mysql::ranges::make_projection_iterator (const Tuple_iterator_t &iterator)
	Factory function to create a Projection_iterator. More...
template<std::size_t index_t, std::ranges::range Source_t>
auto	mysql::ranges::make_projection_view (const Source_t &source)
	Factory function to create a Projection_view. More...
auto	mysql::ranges::make_key_iterator (const auto &iterator)
	Factory function to create a new iterator from a given iterator over pairs. More...
auto	mysql::ranges::make_key_view (const auto &source)
	Factory function to create a new view over the keys in a range of pairs. More...
auto	mysql::ranges::make_mapped_iterator (const auto &iterator)
	Factory function to create a new iterator from a given iterator over pairs. More...
auto	mysql::ranges::make_mapped_view (const auto &source)
	Factory function to create a new view over the mapped values in a range of pairs. More...
