Enum Refusal 

pub enum Refusal {
    OverBudgetGaussian {
        dim: usize,
        cap: usize,
    },
    NoLinearStructure,
}

Why a lower-bound certificate was not issued — the documented refusal that makes the Chaitin ceiling operational. A refusal is never a claim that no bound exists; it is an honest “this is beyond what I can re-check within budget.”

Variants

OverBudgetGaussian

The GF(2) system exceeds the budget’s variable cap (par32-scale needs the incremental engine).

Fields

dim: usize

cap: usize

NoLinearStructure

There is no linear (parity) structure in the formula to certify rigid.

Trait Implementations

impl Clone for Refusal

fn clone(&self) -> Refusal

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Refusal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Refusal

fn eq(&self, other: &Refusal) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
