Failure while driving or asserting a typed crate::Scenario.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Recipe(RecipeError)

Binding the recipe for the scenario failed.

Handle(HandleError)

A typed frame write or endpoint lookup used an invalid runtime handle.

MissingSignal

An expectation ran before the scenario had produced a sample for the path.

Fields

path: String

Host path selected through the recipe’s typed ports.

tick: u64

Scenario frame that was being inspected.

UnexpectedSignal

A signal sample did not have the expected value.

Fields

path: String

Host path selected through the recipe’s typed ports.

expected: Signal

Expected sample.

actual: Signal

Sample produced by the runtime.

tick: u64

Scenario frame that produced the sample.

ExpectedTruthy

A signal sample was present but falsey.

Fields

path: String

Host path selected through the recipe’s typed ports.

actual: Signal

Falsey sample produced by the runtime.

tick: u64

Scenario frame that produced the sample.

UnexpectedEmits

A command was emitted a different number of times than expected.

Fields

command: String

Command selected through the recipe’s typed ports.

expected: usize

Expected number of emits in the current frame.

actual: usize

Actual number of emits in the current frame.

tick: u64

Scenario frame that produced the emits.

Trait Implementations

impl Clone for ScenarioError

fn clone(&self) -> ScenarioError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScenarioError

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

Formats the value using the given formatter.

impl Display for ScenarioError

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

Formats the value using the given formatter.

impl Error for ScenarioError

Available on crate feature std only.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<HandleError> for ScenarioError

fn from(value: HandleError) -> Self

Converts to this type from the input type.

impl From<RecipeError> for ScenarioError

fn from(value: RecipeError) -> Self

Converts to this type from the input type.

impl PartialEq for ScenarioError

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

Equality operator ==.

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

Inequality operator !=.
