[−][src]Trait arithmetic_eval::arith::DoubleWidth

pub trait DoubleWidth: Sized + Unsigned {
    type Wide: Copy + From<Self> + TryInto<Self> + NumOps + Unsigned;
    type SignedWide: Copy + From<Self> + TryInto<Self> + NumOps + Zero + One + Signed + PartialOrd;
}

Encapsulates extension of an unsigned integer type into signed and unsigned double-width types. This allows performing certain operations (e.g., multiplication) without a possibility of integer overflow.
