Enum Feasibility 

pub enum Feasibility {
    None,
    One,
    Many,
}

Saturating feasibility count for a component: none, exactly one, or many satisfying assignments. Deliberately separate from score ambiguity — a component can be uniquely feasible with an ambiguous maximum, or plurally feasible with a unique maximum.

Trait Implementations

impl Clone for Feasibility

fn clone(&self) -> Feasibility

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Feasibility

impl Debug for Feasibility

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

Formats the value using the given formatter.

impl Eq for Feasibility

impl PartialEq for Feasibility

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