source · pub static ARITHMETIC_OVERFLOW: &'static Lint
Expand description
The arithmetic_overflow
lint detects that an arithmetic operation
will overflow.
Example
ⓘ
1_i32 << 32;
{{produces}}
Explanation
It is very likely a mistake to perform an arithmetic operation that overflows its value. If the compiler is able to detect these kinds of overflows at compile-time, it will trigger this lint. Consider adjusting the expression to avoid overflow, or use a data type that will not overflow.
