Struct NewSpan

Source
pub struct NewSpan { /* private fields */ }
Expand description

A mock new span.

Note: This struct contains expectations that can only be asserted on when expecting a new span via MockCollector::new_span. They cannot be validated on MockCollector::enter, MockCollector::exit, or any other method on MockCollector that takes an ExpectedSpan.

For more details on how to use this struct, see the documentation on the collector module.

Implementations§

Source§

impl NewSpan

Source

pub fn with_ancestry(self, ancestry: ExpectedAncestry) -> NewSpan

Configures this NewSpan to expect the specified ExpectedAncestry. A span’s ancestry indicates whether it has a parent or is a root span and whether the parent is explitly or contextually assigned.

For more information and examples, see the documentation on ExpectedSpan::with_ancestry.

Source

pub fn with_fields<I>(self, fields: I) -> NewSpan
where I: Into<ExpectedFields>,

Adds fields to expect when matching a span.

For more information and examples, see the documentation on ExpectedSpan::with_fields.
