Reference
boost::redis::request::push_range
Appends a new command to the end of the request.
Synopsis
Declared in <boost/redis/request.hpp>
template<class ForwardIterator>
void
push_range(
std::string_view cmd,
std::string_view key,
ForwardIterator begin,
ForwardIterator end,
std::iterator_traits<ForwardIterator>::value_type* = nullptr);
Description
This overload is useful for commands that have a key and have a dynamic range of arguments. For example:
std::map<std::string, std::string> map
{ {"key1", "value1"}
, {"key2", "value2"}
, {"key3", "value3"}
};
request req;
req.push_range("HSET", "key", map.cbegin(), map.cend());
Command arguments should either be convertible to std::string_view or support the boost_redis_to_bulk function. This function is a customization point that must be made available using ADL and must have the following signature:
void boost_redis_to_bulk(std::string& to, T const& t);
