Trait Implementations

impl<Input: Clone> Clone for Error<Input> where
    Input: Display, 

fn clone(&self) -> Error<Input>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Input: Debug> Debug for Error<Input> where
    Input: Display, 

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

Formats the value using the given formatter.

impl<Input> Display for Error<Input> where
    Error<Input>: Display,
    UnknownParameterError<Input>: Display,
    Input: Display, 

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

Formats the value using the given formatter.

impl<Input> Error for Error<Input> where
    Error<Input>: Debug + Display + Error + 'static,
    UnknownParameterError<Input>: Debug + Display + Error + 'static,
    Error<Input>: Debug + Display,
    Input: Display, 

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()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
