/// Helper trait used to add `unsigned()` methods to primitive signed integer
/// types.
///
/// The purpose of this trait is to signal the intent that the sign bit of a
/// signed integer is intended to be discarded and the value is instead
/// understood to be a "bag of bits" where the conversion to an unsigned number
/// is intended to be lossless. This can be used for example when converting a
/// signed integer into a larger width with zero-extension.
pub trait Unsigned {
    /// The unsigned integer for this type which has the same width.
    type Unsigned;

    /// View this signed integer as an unsigned integer of the same width.
    ///
    /// All bits are preserved.
