Enum MatchClass 

pub enum MatchClass {
    Satisfies,
    NearMissPatch(u32),
    NearMissMinor(u32),
    Breaking,
    Unknown,
}

Outcome of classifying a request against one declared constraint.

Variants

Satisfies

The request satisfies / intersects the declared constraint.

NearMissPatch(u32)

Disjoint at patch level (after the 0.x role shift); distance in patches.

NearMissMinor(u32)

Disjoint at minor level (after the 0.x role shift); distance in minors.

Breaking

Disjoint at major level (or 0.x minor / 0.0.x patch): incompatible.

Unknown

The declared constraint failed to parse — unknowable.

Trait Implementations

impl Clone for MatchClass

fn clone(&self) -> MatchClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MatchClass

impl Debug for MatchClass

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

Formats the value using the given formatter.

impl Eq for MatchClass

impl PartialEq for MatchClass

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