Struct CheckedArithmetic

Source 
pub struct CheckedArithmetic<Kind = Checked>(/* private fields */);
Expand description

Arithmetic on an integer type (e.g., i32) that checks overflow and other failure conditions for all operations.

As an example, this type implements Arithmetic for all built-in integer types with a definite size (u8, i8, u16, i16, u32, i32, u64, i64, u128, i128).

The type param defines how negation should be performed; it should be one of Checked (default value), Unchecked or NegateOnlyZero. See the docs for these types for more details.
