Fix CreateFullPath to have its intended previous behavior (whatever
that was), and deprecate it in favor of the new CreateDirs function.
Unlike CreateDir, CreateDirs is marked as [[nodiscard]] to avoid new
code ignoring its result value.
Converts creation and deletion functions over to std::filesystem,
simplifying our file-handling code.
Notably with this, CopyDir will now function on Windows.
Simplifies and removes some casts. In all cases, these were generally
widening from a 32-bit unsigned type to a 64-bit unsigned type, so no
information would be lost from the conversion.
fmt now automatically prints the numeric value of an enum class member
by default, so we don't need to use casts any more.
Reduces the line noise a bit.
Since this is inside a string literal, backslashes that are part of
regex syntax have to be escaped. But that's ugly, so convert to a raw
string instead.
Actually, two enum classes, since for some reason there are two separate
yet identical `PollFD` types used in the codebase. I get that one is
ABI-compatible with the Switch while the other is an abstract type used
for the host, but why not use `WSAPOLLFD` directly for the latter?
Anyway, why make this change? Because on Apple platforms, `POLL_IN`,
`POLL_OUT`, etc. (with an underscore) are defined as macros in
<sys/signal.h>. (This is inherited from FreeBSD.) So defining
a variable with the same name causes a compile error.
I could just rename the variables, but while I was at it I thought I
might as well switch to an enum for stronger typing.
Also, change the type used for values copied directly to/from the
`events` and `revents` fields of the host *native*
`pollfd`/`WSASPOLLFD`, from `u32` to `short`, as `short` is the correct
canonical type on both Unix and Windows.
`PhysicalCore`'s move assignment operator was declared as `= default`,
but was implicitly deleted because `PhysicalCore` has fields
of reference type. Switch to explicitly deleting it to avoid a Clang
warning.
The move *constructor* is still defaulted, and is required to exist due
to the use of `std::vector<PhysicalCore>`.
- Add a type check so that calling Push with an invalid type produces a
compile error rather than a linker error.
- vi.cpp was calling Push with a variable of type `std::size_t`.
There's no explicit overload for `size_t`, but there is one for `u64`,
which on most platforms is the same type as `size_t`. On macOS,
however, it isn't: both types are 64 bits, but `size_t` is `unsigned
long` and `u64` is `unsigned long long`. Regardless, it makes more
sense to explicitly use `u64` here instead of `size_t`.
