Enum TestError 

pub enum TestError {
    Setup(String),
    Load(String),
    Run(String),
    Mismatch(String),
}

Why a rule test could not run, or did not hold.

Variants

Setup(String)

The harness could not set up its temporary project.

Load(String)

The rule or its config failed to load.

Distinct from a failed assertion: the rule never ran, so nothing was proven either way, and reporting it as “no violations found” would be actively misleading.

Run(String)

The run aborted — a rule threw, or breached a budget.

Mismatch(String)

The rule reported something other than what was expected.

Trait Implementations

impl Clone for TestError

fn clone(&self) -> TestError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TestError

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

Formats the value using the given formatter.

impl Eq for TestError

impl Error for TestError

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 TestError

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

Equality operator ==.

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

Inequality operator !=.
