Struct ErrorImpl 

pub struct ErrorImpl<E> { /* private fields */ }

A struct that wraps an error together with a backtrace and an optional description

Implementations

impl<E> ErrorImpl<E>

pub fn new(err: E, desc: String) -> Self

Captures a backtrace and creates a new error

pub fn new_static(err: E, desc: &'static str) -> Self

Captures a backtrace and creates a new error with a static description

pub const fn with_backtrace( err: E, desc: Cow<'static, str>, backtrace: Option<Backtrace>, ) -> Self

Creates a new error with the given backtrace

pub const fn err(&self) -> &E

The wrapped error

pub const fn desc(&self) -> &Cow<'static, str>

The error description

pub fn backtrace(&self) -> Option<&Backtrace>

The underlying backtrace

Trait Implementations

impl<E> Clone for ErrorImpl<E>

where E: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E> Debug for ErrorImpl<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> Default for ErrorImpl<E>

where E: Default + Display,

fn default() -> Self

Returns the “default value” for a type.

impl<E> Deref for ErrorImpl<E>

type Target = E

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<E> Display for ErrorImpl<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Error for ErrorImpl<E>

where E: Error,

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<E> From<E> for ErrorImpl<E>

where E: Display,

fn from(error: E) -> Self

Converts to this type from the input type.

impl From<Error> for ErrorImpl<ErrorKind>

fn from(underlying: Error) -> Self

Converts to this type from the input type.
