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

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;
}
Expand description

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.

Associated Types

type Wide: Copy + From<Self> + TryInto<Self> + NumOps + Unsigned[src]

Unsigned double-width extension type.

type SignedWide: Copy + From<Self> + TryInto<Self> + NumOps + Zero + One + Signed + PartialOrd[src]

Signed double-width extension type.
