struct impl::route_params_accessor_t

Detailed Description

Parameters extracted from route.

Holds values of parameters extracted from route.

All values are stored as string views, route_params_t instance owns bufers used by these views. And that leads to following limittions: once a copy of a string view is created it is important to use it with respect to life time of route_params_t instance to which this parameter bind belongs. String view is valid during route_params_t instance life time.

◆ m_request_target

std::unique_ptr< char[] > restinio::router::route_params_t::m_request_target

A raw request target.

All parameters values are defined as string views refering parts of this beffer.

std::unique_ptr< char[] > is used here on purpose, because if we consider std::string, then it has an issue when SSO is applied. It is important that parameters that refering buffer are valid after move operations with the buffer. And std::strings with SSO applied cannot guarantee this. Vector on the other hand gives this guarantee.
