Struct AssertFailure 

pub struct AssertFailure { /* private fields */ }

An error describing a failed assertion.

This struct implements the std::error::Error trait.

Implementations

impl AssertFailure

pub fn description(&self) -> Option<&String>

Returns the description of the assertion that failed.

pub fn message(&self) -> &str

Returns the failure message of the assertion that failed.

pub fn location(&self) -> Option<&OwnedLocation>

Returns the location of the assertion in the source code / test code if it has been set in the Spec.

Trait Implementations

impl Clone for AssertFailure

fn clone(&self) -> AssertFailure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssertFailure

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

Formats the value using the given formatter.

impl Display for AssertFailure

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

Formats the value using the given formatter.

impl Error for AssertFailure

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 AssertFailure

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