[−][src]Struct prometheus_parser::Operator
A binary operator expression with left- and right-hand sides.
Operator expressions may optionally have a matching clause for more specific vector matching behavior.
Note that operator precedence is accounted for at parse-time, so the resulting tree (i.e. lhs/rhs expressions) should already account for un-grouped expressions at the same syntax level.
Fields
kind: OperatorKind
This Operator's function (multiply, divide, power, equals, etc)
lhs: BExpression
The left-hand-side expression
rhs: BExpression
The right-hand-side expression
matching: Option<Matching>
An optional matching clause for this operator (on(...)
, ignoring(...)
)
span: Option<Span>
