Struct tracing_mock::span::NewSpan

pub struct NewSpan { /* private fields */ }

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

impl NewSpan

pub fn with_explicit_parent(self, parent: Option<&str>) -> NewSpan

Configures this ExpectedSpan to expect an explicit parent span or to be an explicit root.

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

pub fn with_contextual_parent(self, parent: Option<&str>) -> NewSpan

Configures this NewSpan to expect a contextually-determined parent span, or to be a contextual root.

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

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.

Trait Implementations

impl Debug for NewSpan

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NewSpan

fn default() -> NewSpan

Returns the “default value” for a type.

impl Display for NewSpan

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ExpectedSpan> for NewSpan

fn from(span: ExpectedSpan) -> Self

Converts to this type from the input type.

impl PartialEq for NewSpan

fn eq(&self, other: &NewSpan) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for NewSpan
