Typedef Documentation

◆ SelectSize

using compiler::SelectSize = SelectValue<std::size_t>

Alias for std::size_t values selection for the current compiler and standard library.

Definition at line 107 of file select.hpp.

Function Documentation

◆ GetTypeName()

template<typename T >
std::string compiler::GetTypeName ( )

Returns a human-readable representation of provided type name.

GetTypeName(typeidT)) outputs the type, not the alias. For std::chrono functions it gives unreadable results: std::chrono::duration<long, std::ratio<1l, 1l> > - it's seconds

The GetTypeName<T>() provides a more readable output.
