Trait Implementations

impl<E: Debug + AsErrorSource> Debug for Error<E>

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

Formats the value using the given formatter.

impl<E: AsErrorSource> Display for Error<E>

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

Formats the value using the given formatter.

impl<E: AsErrorSource> Error for Error<E> 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.

fn provide(&'a self, req: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl<E: AsErrorSource> ErrorCompat for Error<E>

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.

impl<E: AsErrorSource> From<E> for Error<E>

fn from(error: E) -> Self

Converts to this type from the input type.
