Struct shared_failure::SharedFailure

pub struct SharedFailure(_);

Failure that can be cloned and shared across thread boundaries.

Methods

impl SharedFailure

pub fn from_fail<T: Fail>(err: T) -> SharedFailure

Wraps the provided error into a SharedFailure.

pub fn downcast_ref<T: Fail>(&self) -> Option<&T>

Attempts to downcast this SharedFailure to a particular Fail type by reference.

If the underlying error is not of type T, this will return None.

Trait Implementations

impl Clone for SharedFailure

fn clone(&self) -> SharedFailure

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SharedFailure

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Fail for SharedFailure

fn cause(&self) -> Option<&Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.

impl Display for SharedFailure

fn fmt(&self, f: &mut Formatter) -> FmtResult

Formats the value using the given formatter.

impl From<Error> for SharedFailure

fn from(err: Error) -> SharedFailure

Performs the conversion.
