Struct error_chain::example_generated::Error

pub struct Error(_, _);

The Error type.

This struct is made of three things:

• an ErrorKind which is used to determine the type of the error.
• a backtrace, generated when the error is created.
• an error chain, used for the implementation of Error::cause().

Methods

impl Error

fn from_kind(kind: ErrorKind) -> Error

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

fn kind(&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.

Methods from Deref<Target=ErrorKind>

fn description(&self) -> &str

A string describing the error kind.
