Struct 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 MockSubscriber::new_span. They cannot be validated on MockSubscriber::enter, MockSubscriber::exit, or any other method on MockSubscriber that takes an ExpectedSpan.

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

Implementations

impl NewSpan

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.

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<S> From<S> for NewSpan

where S: Into<ExpectedSpan>,

fn from(span: S) -> Self

Converts to this type from the input type.

impl PartialEq for NewSpan

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

Tests for self and other values to be equal, and is used by ==.

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

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