Struct libimagnotes::error::NoteError

pub struct NoteError(pub NoteErrorKind, _);

The Error type.

This tuple struct is made of two elements:

• an ErrorKind which is used to determine the type of the error.
• An internal State, not meant for direct use outside of error_chain internals, containing:
  • a backtrace, generated when the error is created.
  • an error chain, used for the implementation of Error::cause().

Methods

impl NoteError

fn from_kind(kind: NoteErrorKind) -> NoteError

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

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

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

fn kind(&self) -> &NoteErrorKind

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 = NoteErrorKind>

fn description(&self) -> &str

A string describing the error kind.
