Enum proptest::test_runner::TestError

pub enum TestError<T> {
    Abort(Reason),
    Fail(Reason, T),
}

A failure state from running test cases for a single test.

Variants

Abort(Reason)

The test was aborted for the given reason, for example, due to too many inputs having been rejected.

Fail(Reason, T)

A failing test case was found. The string indicates where and/or why the test failed. The T is the minimal input found to reproduce the failure.

Trait Implementations

impl<T: Clone> Clone for TestError<T>

fn clone(&self) -> TestError<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for TestError<T>

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

Formats the value using the given formatter.

impl<T: Debug> Display for TestError<T>

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

Formats the value using the given formatter.

impl<T: Debug> Error for TestError<T>

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

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

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<T: PartialEq> PartialEq for TestError<T>

fn eq(&self, other: &TestError<T>) -> 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.
