Enum StepError 

#[non_exhaustive]
pub enum StepError {
    MissingFixture {
        name: String,
        ty: String,
        step: String,
    },
    ExecutionError {
        pattern: String,
        function: String,
        message: String,
    },
    PanicError {
        pattern: String,
        function: String,
        message: String,
    },
}

Error type produced by step wrappers.

The variants categorize the possible failure modes when invoking a step.

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.

MissingFixture

Raised when a required fixture is absent from the StepContext.

Fields

name: String

Name of the missing fixture.

ty: String

Type of the missing fixture.

step: String

Step function that requested the fixture.

ExecutionError

Raised when the invoked step function returns an Err variant.

Fields

pattern: String

Pattern text used when invoking the step.

function: String

Name of the step function.

message: String

Error message produced by the step function.

PanicError

Raised when the step function panics during execution.

Fields

pattern: String

Pattern text used when invoking the step.

function: String

Name of the step function.

message: String

Panic payload converted to a string.

Implementations

impl StepError

pub fn format_with_loader(&self, loader: &FluentLanguageLoader) -> String

Render the error message using the provided Fluent loader.

Examples

let loader: FluentLanguageLoader = {
    let mut loader = fluent_language_loader!();
    i18n_embed::select(&loader, &Localizations, &[langid!("en-US")]).unwrap();
    loader
};
let error = StepError::MissingFixture {
    name: "db".into(),
    ty: "Pool".into(),
    step: "Given a database".into(),
};
let message = error.format_with_loader(&loader);
// Check the key components (name, type, step) rather than exact format.
assert!(message.contains("db"));
assert!(message.contains("Pool"));
assert!(message.contains("Given a database"));

Trait Implementations

impl Clone for StepError

fn clone(&self) -> StepError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StepError

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

Formats the value using the given formatter.

impl Display for StepError

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

Formats the value using the given formatter.

impl Error for StepError

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 PartialEq for StepError

fn eq(&self, other: &StepError) -> 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.
