Struct Error

pub struct Error(/* private fields */);

This crate specific error type.

Methods from Deref<Target = TrackableError<ErrorKind>>

pub fn kind(&self) -> &K

Returns the kind of this error.

pub fn concrete_cause<T>(&self) -> Option<&T>

where T: Error + 'static,

Tries to return the cause of this error as a value of T type.

If neither this error has a cause nor it is an T value, this method will return None.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for TrackableError<ErrorKind>

fn from(f: Error) -> Self

Converts to this type from the input type.

impl From<ErrorKind> for Error

fn from(f: ErrorKind) -> Self

Converts to this type from the input type.

impl From<TrackableError<ErrorKind>> for Error

fn from(f: TrackableError<ErrorKind>) -> Self

impl Trackable for Error

type Event = Location

Event type which a history of an instance of this type can have.

fn history(&self) -> Option<&History<Self::Event>>

Returns the reference of the tracking history of this instance.

fn history_mut(&mut self) -> Option<&mut History<Self::Event>>

Returns the mutable reference of the tracking history of this instance.

fn track<F>(&mut self, f: F)

where F: FnOnce() -> Self::Event,

Add an event into the tail of the history of this instance.

fn in_tracking(&self) -> bool

Returns true if it is being tracked, otherwise false.

impl Deref for Error

type Target = TrackableError<ErrorKind>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
