impl Eq for Error

impl Error for Error[+]

[+] Show hidden undocumented items

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error[+]

[+] Show hidden undocumented items

fn from(err: Error) -> Error[−]

Performs the conversion.

impl PartialEq<Error> for Error[+]

[+] Show hidden undocumented items

fn eq(&self, other: &Error) -> bool[−]

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Error) -> bool[−]

This method tests for !=.
