    ManyToOne(Labels),
    OneToMany(Labels),
    ManyToMany,
}

The label list provided with the group_left or group_right modifier contains additional labels from the “one”-side to be included in the result metrics.

Trait Implementations

impl Clone for VectorMatchCardinality

fn clone(&self) -> VectorMatchCardinality

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VectorMatchCardinality

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

Formats the value using the given formatter.

impl PartialEq<VectorMatchCardinality> for VectorMatchCardinality

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

This method tests for self and other values to be equal, and is used by ==.

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

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