Trait Implementations

impl Debug for DaemonError

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

Formats the value using the given formatter.

impl Display for DaemonError

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

impl Error for DaemonError where
    Self: Debug + Display, 

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

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

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

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

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

impl ErrorCompat for DaemonError

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

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_> where
    Self: AsErrorSource, 

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
