text_encoding::aliases_view
class text_encoding::aliases_view
: public ranges::view_interface <text_encoding::aliases_view>
(since C++26)
: public ranges::view_interface <text_encoding::aliases_view>
The nested class text_encoding::aliases_view is a view over aliases of the character encoding.
Let r denote an instance of aliases_view. For a non-empty range r:
- r.front() is the primary name of the registered character encoding,
- r contains the aliases of the registered character encoding such that the order of the aliases is unspecified,
- each element in r is a non-null and non-empty null-terminated byte string encoded in the literal character encoding and comprising only characters from the basic character set, and
- r does not contain duplicate values when compared with std::strcmp .
These are the following type properties of text_encoding::aliases_view:
- it models
copyable,random_access_range, andborrowed_range. - it is not required to satisfy
common_rangeanddefault_initializable. - both ranges::range_value_t <text_encoding::aliases_view> and ranges::range_reference_t <text_encoding::aliases_view> denote const char*.
- ranges::iterator_t <text_encoding::aliases_view> is a ConstexprIterator.
