Struct throw::Error

pub struct Error<E> { /* fields omitted */ }

Represents an error. Stores an original error of type E, and any number of ErrorPoints at which the error was propagated.

Methods

impl<E> Error<E>

pub fn new(error: E) -> Error<E>

Creates a new Error with no ErrorPoints

pub fn get_context(&self) -> &[KvPair]

pub fn points(&self) -> &[ErrorPoint]

Gets all ErrorPoints where this Error was thrown. These are in reverse order, with the first time it was thrown first and the latest time it was thrown last.

pub fn original_error(&self) -> &E

Deprecated

Gets the original error which this Error was constructed with.

pub fn error(&self) -> &E

Gets the original error which this Error was constructed with.

pub fn into_origin(self) -> E

Move the original error out.

pub fn into_error<N>(self) -> N where     E: Into<N>,

Take out the original error and transform into another type where the original error can transform into that type.

pub fn transform<NE>(self) -> Error<NE> where     E: Into<NE>,

Transforms this Error into Error. This isn't implemented as an Into or From implementation because it would conflict with the blanket implementations in stdlib.

Trait Implementations

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

Formats the value using the given formatter.

impl<E> Debug for Error<E> where     E: Debug,

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

Formats the value using the given formatter.

impl<E> Error for Error<E> where     E: Error,

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&Error>

The lower-level cause of this error, if any.
