Struct trackable::error::IoError

pub struct IoError(_);

A variant of std::io::Error that implements Trackable trait.

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 IoError

pub fn clone(&self) -> IoError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IoError

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

Formats the value using the given formatter.

impl Deref for IoError

type Target = TrackableError<ErrorKind>

The resulting type after dereferencing.

pub fn deref(&self) -> &<IoError as Deref>::Target

Dereferences the value.

impl Display for IoError

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

Formats the value using the given formatter.

impl Error for IoError

pub 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
