}

Edge-weight type for the blossom solver: a signed integer wide enough to hold the caller’s largest weight without overflow.

Required Associated Constants

const ZERO: Self

const ONE: Self

Required Methods

fn inf() -> Self

Larger than any edge slack that can arise, but small enough to leave headroom against overflow when doubled.

fn double(self) -> Self

self * 2, used when doubling dual-variable adjustments.

fn half(self) -> Self

self / 2, used when halving slack to keep duals integral.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
