Enum UncertaintyReason 

pub enum UncertaintyReason {
    RealSign,
    Predicate,
    Ordering,
    Boundary,
    Unsupported,
}

Reason an operation could not decide a topology branch.

Variants

RealSign

A Real sign could not be proven under the active policy.

Predicate

Predicate policy could not decide the branch.

Ordering

Parameter ordering could not be decided.

Boundary

The query lies on a boundary where the requested Real result is undefined.

Unsupported

The requested operation is not supported by this slice.

Trait Implementations

impl Clone for UncertaintyReason

fn clone(&self) -> UncertaintyReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UncertaintyReason

impl Debug for UncertaintyReason

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

Formats the value using the given formatter.

impl Eq for UncertaintyReason

impl PartialEq for UncertaintyReason

fn eq(&self, other: &UncertaintyReason) -> 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.
