Enum promql_parser::parser::ast::LabelModifier

pub enum LabelModifier {
    Include(Labels),
    Exclude(Labels),
}

LabelModifier acts as

Aggregation Modifier

• Exclude means ignoring
• Include means on

Vector Match Modifier

• Exclude means without removes the listed labels from the result vector, while all other labels are preserved in the output.
• Include means by does the opposite and drops labels that are not listed in the by clause, even if their label values are identical between all elements of the vector.

if empty listed labels, meaning no grouping

Variants

Include(Labels)

Exclude(Labels)

Trait Implementations

impl Clone for LabelModifier

fn clone(&self) -> LabelModifier

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LabelModifier

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

Formats the value using the given formatter.

impl PartialEq<LabelModifier> for LabelModifier

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