Trait Implementations

impl<C: Clone> Clone for ErrKind<C>

fn clone(&self) -> ErrKind<C>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<C> Debug for ErrKind<C>

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

Formats the value using the given formatter.

impl<C> Display for ErrKind<C>

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

Formats the value using the given formatter.

impl<C> Error for ErrKind<C>

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 description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
