    // The type of query if this is a query expression
    QueryType *string `json:"queryType,omitempty"`
    RelativeTimeRange *alertingv0alpha1.RelativeTimeRange `json:"relativeTimeRange,omitempty"`

    // Used to mark the expression to be used as the final source for the rule evaluation

Methods🔗

UnmarshalJSONStrict🔗

UnmarshalJSONStrict implements a custom JSON unmarshalling logic to decode Expression from JSON.

Note: the unmarshalling done by this function is strict. It will fail over required fields being absent from the input, fields having an incorrect type, unexpected fields being present, …

func (expression *Expression) UnmarshalJSONStrict(raw []byte) error

Equals🔗

Equals tests the equality of two Expression objects.

func (expression *Expression) Equals(other Expression) bool

Validate🔗

Validate checks all the validation constraints that may be defined on Expression fields for violations and returns them.

func (expression *Expression) Validate() error
