Enum SignEncoding 

pub enum SignEncoding {
    Absent,
    Magnitude,
    TwosComplement,
}

How the sign of a stored number is encoded.

Variants

Absent

No sign bit: the layout is unsigned and width() has no sign bit (uint).

Magnitude

A sign bit above the other fields selects the sign of the magnitude, so zero has two encodings (every IEEE-family float; sign-magnitude integers).

TwosComplement

A sign bit of weight -2^(mantissa_bits) over the mantissa field: the range is asymmetric and zero has one encoding (int8 and the other native integers).
