The first argument of Checked, e.g. int if the left-hand side of the operator is Checked!int
The right-hand side type involved in the operator
In all cases, returns lhs < rhs ? -1 : lhs > rhs. The result is not autocorrected in case of an erroneous comparison.
1 auto x = checked!Warn(-42); 2 // Passes 3 assert(x <= -42); 4 // Passes but prints a warning 5 // assert(x <= uint(-42));
Called automatically upon a comparison for ordering using one of the operators <, <=, >, or >=. In case the comparison is erroneous (i.e. it would make a signed negative value appear greater than or equal to an unsigned positive value), then a warning message is printed to stderr.
