Types

Comparator

Set of valid comparison operators. FUTURE: possible we may want a good ol’ ‘==’ 🤷‍♂️. Not yet atleast and YAGNI.

pub type Comparator {
  LessThan
  LessThanOrEqualTo
  GreaterThan
  GreaterThanOrEqualTo
}

Constructors

```

LessThanOrEqualTo
```

GreaterThan
```
```
GreaterThanOrEqualTo
```

Primitives

</>

Supported primitive query types that can be resolved from CQL expressions. Each primitive represents a specific SLO calculation pattern.

pub type Primitives {
  GoodOverTotal(numerator: parser.Exp, denominator: parser.Exp)
  TimeSlice(
    comparator: Comparator,
    interval_in_seconds: Int,
    threshold: Float,
    query: String,
  )
}

Constructors

```
GoodOverTotal(numerator: parser.Exp, denominator: parser.Exp)
```
Good over total requires a top level division operator. Represents an SLO where the numerator is the “good” events and the denominator is the “total” events.

TimeSlice(
  comparator: Comparator,
  interval_in_seconds: Int,
  threshold: Float,
  query: String,
)
