Struct trackable::error::Failure

pub struct Failure(_);

TrackableError type specialized for Failed.

Implementations

impl Failure

pub fn from_error<E>(error: E) -> Self where
    E: Into<BoxError>, 

Makes a new Failure instance which was caused by the error.

Methods from Deref<Target = TrackableError<Failed>>

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 Failure

fn clone(&self) -> Failure

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Failure

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

Formats the value using the given formatter.

impl Deref for Failure

type Target = TrackableError<Failed>

The resulting type after dereferencing.

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

Dereferences the value.

impl<'de> Deserialize<'de> for Failure

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for Failure

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

Formats the value using the given formatter.

impl Error for Failure

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

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

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

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
