Implementations§
Source§impl Error
impl Error
Sourcepub fn erase<T: Error + Send + Sync + Debug + 'static>(input: T) -> Self
pub fn erase<T: Error + Send + Sync + Debug + 'static>(input: T) -> Self
Creates a new Error with the provided concrete input value.
Sourcepub fn downcast_ref<T: Error + Send + Sync + Debug + 'static>(
&self,
) -> Option<&T>
pub fn downcast_ref<T: Error + Send + Sync + Debug + 'static>( &self, ) -> Option<&T>
Downcasts to the concrete input value.
Sourcepub fn downcast_mut<T: Error + Send + Sync + Debug + 'static>(
&mut self,
) -> Option<&mut T>
pub fn downcast_mut<T: Error + Send + Sync + Debug + 'static>( &mut self, ) -> Option<&mut T>
Downcasts to the concrete input value.
Sourcepub fn downcast<T: Error + Send + Sync + Debug + 'static>(
self,
) -> Result<T, Self>
pub fn downcast<T: Error + Send + Sync + Debug + 'static>( self, ) -> Result<T, Self>
Downcasts to the concrete input value.
Sourcepub fn doesnt_matter() -> Self
Available on crate feature test-util only.
pub fn doesnt_matter() -> Self
test-util only.Returns a Error with a fake/test value with the expectation that it won’t be downcast in the test.
