Trait Implementations

impl<T: Clone + ?Sized + 'static> Clone for ExampleErrorStruct<T>

fn clone(&self) -> ExampleErrorStruct<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + ?Sized + 'static> Debug for ExampleErrorStruct<T>

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

Formats the value using the given formatter.

impl<T: Default + ?Sized + 'static> Default for ExampleErrorStruct<T>

fn default() -> ExampleErrorStruct<T>

Returns the "default value" for a type.

impl<T: Display + ?Sized + 'static> Display for ExampleErrorStruct<T>

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

Formats the value using the given formatter.

impl<T: Eq + ?Sized + 'static> Eq for ExampleErrorStruct<T>

impl<T> Error for ExampleErrorStruct<T> where
    T: Error + 'static, 

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
