pub trait Signed {
type Signed;
// Required method
fn signed(self) -> Self::Signed;
}Expand description
Helper trait used to add signed() methods to primitive unsigned integer
types.
The purpose of this trait is to signal the intent that the sign bit of an unsigned integer is intended to be discarded and the value is instead understood to be a “bag of bits” where the conversion to a signed number is intended to be lossless bit-wise. This can be used for example when converting an unsigned integer into a signed integer for constrained reasons outside the scope of the code in question.
