Struct Bug 

pub struct Bug(/* private fields */);

Programming error (a bug)

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.

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 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 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
