Set the host to an address.
url_base& set_host_address( string_view s);
Depending on the contents of the passed string, this function sets the host:
host_type::ipv4
.
host_type::ipv6
.
host_type::ipvfuture
.
host_type::name
.
In all cases, when this function returns, the URL contains an authority.
assert( url( "http://www.example.com" ).set_host_address( "127.0.0.1" ).buffer() == "http://127.0.0.1" );
this->has_authority() == true
Linear in s.size()
.
Strong guarantee. Calls to allocate may throw.
