Function std.checkedint.Throw.onOverflow

Called automatically upon an overflow during a unary or binary operation.

typeof(~Lhs()) onOverflow(string x, Lhs) (
  Lhs lhs
);

typeof(Lhs()+Rhs()) onOverflow(string x, Lhs, Rhs) (
  Lhs lhs,
  Rhs rhs
);

Parameters

NameDescription
x The operator, e.g. -
lhs The left-hand side (or sole) argument
rhs The right-hand side type involved in the operator

Returns

Nominally the result is the desired value of the operator, which will be forwarded as result. For Throw, the function never returns because it throws an exception.
