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

[−]

Formats the value using the given formatter.

impl Fail for DbError

[+]

fn cause(&self) -> Option<&(Fail + 'static)>

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>

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.
