pub enum Cause<E> {
    Disprove(E),
    Panic(Option<Cow<'static, str>>),
}

Panic(Option<Cow<'static, str>>)

The test function panicked.

Trait Implementations

impl<E: Clone> Clone for Cause<E>

fn clone(&self) -> Cause<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for Cause<E>

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

Formats the value using the given formatter.

impl<E: PartialEq> PartialEq for Cause<E>

fn eq(&self, other: &Cause<E>) -> 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.
