Today I saw this code, inside a class:
static const uint32_t invalid_index = ~uint32_t();
My question is, what is the return value of a uint32_t destructor, and why is it useful?
That’s not a destructor, but a bitwise
NOToperator applied to a value-initializeduint32_t.A value initialized integral type is
0, so you’re taking the bitwiseNOTof0.Similar to:
