Trait Implementations

impl Debug for SetError

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

Formats the value using the given formatter.

impl Display for SetError

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

Formats the value using the given formatter.

impl Eq for SetError

impl Error for SetError

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 1.41.0:

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

impl PartialEq<SetError> for SetError

fn eq(&self, other: &SetError) -> bool

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

fn ne(&self, other: &SetError) -> bool

This method tests for !=.
