Error type for errors that should be unreachable, indicating a bug.

Use bug to return a Result<T, Bug>.

Implementations

impl Bug

pub fn msg(&self) -> &'static str

Get the message used when creating the Bug.

Trait Implementations

impl Clone for Bug

fn clone(&self) -> Bug

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bug

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

Formats the value using the given formatter.

impl Display for Bug

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

Formats the value using the given formatter.

impl Eq for Bug

impl Error for Bug

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Infallible> for Bug

fn from(err: Infallible) -> Self

Converts to this type from the input type.

impl PartialEq for Bug

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

Equality operator ==.

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