Trait error_chain::ChainedError

pub trait ChainedError: Error + Send + 'static {
    type ErrorKind;
    fn from_kind(kind: Self::ErrorKind) -> Self
    where
        Self: Sized;
    fn with_chain<E, K>(error: E, kind: K) -> Self
    where
        Self: Sized,
        E: Error + Send + 'static,
        K: Into<Self::ErrorKind>;
    fn kind(&self) -> &Self::ErrorKind;
    fn iter(&self) -> ErrorChainIter;
    fn backtrace(&self) -> Option<&Backtrace>;

    fn display<'a>(&'a self) -> Display<'a, Self> { ... }
}

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 where
    Self: Sized, 

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

fn with_chain<E, K>(error: E, kind: K) -> Self where
    Self: Sized,
    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.

fn iter(&self) -> ErrorChainIter

Iterates over the error chain.

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

Returns the backtrace associated with this error.

Provided Methods

fn display<'a>(&'a self) -> Display<'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.
