quick_zstr
fn ZString String.quick_zstr(self) @deprecated("Unsafe, use zstr_tcopy instead")Return a pointer to the string *iff* it is a pointerto a zero terminated string, otherwise return a temp allocated zstring copy.
This function is suitable if you are converting strings to ZString on the temp
allocator, but suspect that the String might actually already point to zero
terminated data.
The function looks one step beyond the end of the slice to determine this,
which means that if that data is then modified after this call, this function
might behave incorrectly.
For this reason, try to ensure that the resulting ZString is immediately used.
