Constructor.
template< class OptionalString> param_view( core::string_view key, OptionalString const& value);
This constructs a parameter with a key and value. No validation is performed on the strings. The new key and value reference the same corresponding underlying character buffers. Ownership of the buffers is not transferred; the caller is responsible for ensuring that the assigned buffers remain valid until they are no longer referenced.
param_view qp( "key" , "value" );
this->key.data() == key.data() && this->value.data() == value.data() && this->has_value == true
Constant.
Throws nothing.
