Hi,
This is a follow up of "[string_ref] Add an equality operator between
string_ref and char*"
I'm sorry for the previous message, I'm started learning C++ and I'm making
some errors
Here the new topic:
boost::string_ref rely on implicit conversation for using operators
For example this operator:
template
bool operator==(basic_string_ref x, basic_string_ref y)
Is bad because if I write this:
boost::string_ref("http") == "http"
The compiler complains:
error: no match for ‘operator==’ (operand types are
‘boost::basic_string_ref’ and ‘const char
[5]’)
It can't find the correct overload because implicit conversion is
considered after candidate templates have been considered
boost::string_ref should offer overloads for string and const char* so it
can be possible write code like
boost::string_ref("boost") == "boost" && boost::string_ref("c++") ==
std::string("c++")
