Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Fail for StoreError

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.

Important traits for Causes<'f>

impl<'f> Iterator for Causes<'f> type Item = &'f (Fail + 'static);

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 StoreError

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

Formats the value using the given formatter.
