Programming error (a bug)

Tuple Fields

0: Box<BugRepr>

Implementations

impl Bug

pub fn new<S: Into<String>>(kind: ErrorKind, message: S) -> Self

Create a bug error report capturing this call site and backtrace

Prefer to use internal!, as that makes it easy to add additional information via format parameters.

fn new_inner( kind: ErrorKind, message: String, source: Option<Arc<dyn Error + Send + Sync + 'static>>, ) -> Self

Create an internal error

pub fn from_error<E, S>(kind: ErrorKind, source: E, message: S) -> Self

where S: Into<String>, E: Error + Send + Sync + 'static,

Create an bug error report from another error, capturing this call site and backtrace

In map_err, and perhaps elsewhere, prefer to use into_internal!, as that makes it easy to add additional information via format parameters.

Trait Implementations

impl Clone for Bug

fn clone(&self) -> Bug

Returns a copy 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 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 HasKind for Bug

fn kind(&self) -> ErrorKind

Return the kind of this error.
