Count expectation for span cardinality validation

Fields

spans_total: Option<CountBound>

Total span count bounds

events_total: Option<CountBound>

Total event count bounds (events across all spans)

errors_total: Option<CountBound>

Total error count bounds (spans with error status)

by_name: Option<HashMap<String, CountBound>>

Per-name count bounds

Implementations

impl CountExpectation

pub fn new() -> Self

Create a new empty CountExpectation

pub fn with_spans_total(self, bound: CountBound) -> Self

Set total spans count bound

pub fn with_events_total(self, bound: CountBound) -> Self

Set total events count bound

pub fn with_errors_total(self, bound: CountBound) -> Self

Set total errors count bound

pub fn with_name_count(self, name: String, bound: CountBound) -> Self

Add a per-name count bound

pub fn validate(&self, spans: &[SpanData]) -> Result<()>

Validate all count expectations against actual spans

Arguments

• spans - Slice of SpanData to validate against

Returns

• Result<()> - Ok if all counts match expectations, Err with detailed message otherwise

Errors

• Count bounds not satisfied
• Error count validation failures
