Many of these constructors don't even need to be templated. The only
ones that need to be templated are the ones that actually make use of
the parameter pack.
Even then, since std::vector accepts an initializer list, we can supply
the parameter pack directly to it instead of creating our own copy of
the list, then copying it again into the std::vector.
Given the class contains quite a lot of non-trivial types, place the
constructor and destructor within the cpp file to avoid inlining
construction and destruction code everywhere the class is used.
Makes the class less surprising when it comes to forward declaring the
type, and also prevents inlining the destruction code of the class,
given it contains non-trivial types.
These are able to be omitted from the declaration of functions, since
they don't do anything at the type system level. The definitions of the
functions can retain the use of const though, since they make the
variables immutable in the implementation of the function where they're
used.
Instead of retrieving the data from the std::variant instance, we can
just check if the variant contains that type of data.
This is essentially the same behavior, only it returns a bool indicating
whether or not the type in the variant is currently active, instead of
actually retrieving the data.
By default, MSVC doesn't use standards-compliant volatile semantics.
This makes it behave in a standards-compliant manner, making
expectations more uniform across compilers.
For similar reasons to the previous change, we move this to a single
function, so we don't need to duplicate the conversion logic in several
places within main.cpp.
Specifies the conversions explicitly to avoid implicit conversions from
const char* to QString. This makes it easier to disable implicit QString
conversions in the future.
In this case, the implicit conversion was technically wrong as well. The
implicit conversion treats the input strings as ASCII characters. This
would result in an incorrect conversion being performed in the rare case
a branch name was created with a non-ASCII Unicode character, likely
resulting in junk being displayed.
The C++ standard allows constexpr variables declared with the extern
keyword to have external linkage. Previously MSVC wasn't abiding by
this. This just makes the compiler more standards compliant during
builds.
Given we currently don't make use of anything that would break by this,
this is safe to enable.
