This trait is implemented on all the errors generated by the error_chain macro.

Associated Types

type ErrorKind

Associated kind type.

Required Methods

fn from_kind(kind: Self::ErrorKind) -> Self

Constructs an error from a kind, and generates a backtrace.

fn with_chain<E, K>(error: E, kind: K) -> Self where
    E: Error + Send + 'static,
    K: Into<Self::ErrorKind>, 

Constructs a chained error from another error and a kind, and generates a backtrace.

fn kind(&self) -> &Self::ErrorKind

Returns the kind of the error.

Important traits for Iter<'a>

impl<'a> Iterator for Iter<'a> type Item = &'a (Error + 'a);

fn iter(&self) -> Iter

Iterates over the error chain.

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

Returns the backtrace associated with this error.

fn chain_err<F, EK>(self, error: F) -> Self where
    EK: Into<Self::ErrorKind>,
    F: FnOnce() -> EK, 

Extends the error chain with a new entry.

Provided Methods

fn display_chain(&'a self) -> DisplayChain<'a, Self>

Returns an object which implements Display for printing the full context of this error.

The full cause chain and backtrace, if present, will be printed.
