Struct Error

pub struct Error<C> { /* private fields */ }

The custom error type for use in Result::{Fail, Abort}. Stores a wrapped err that must implement Display as well as an offset and an optional cause.

Implementations

impl<C> Error<C>

pub fn new<D: Into<String>>(msg: D, ctx: Box<C>) -> Self

Constructs a new Error with an offset and no cause.

pub fn caused_by<'a, D: Into<String>>( msg: D, cause: Box<Self>, ctx: Box<C>, ) -> Self

Constructs a new Error with an offset and a cause.

pub fn get_msg<'a>(&'a self) -> &str

Returns the msg.

pub fn get_cause<'a>(&'a self) -> Option<&'a Error<C>>

Returns Some(cause) if there is one, None otherwise.

pub fn get_context(&self) -> &C

Trait Implementations

impl<C: Clone> Clone for Error<C>

fn clone(&self) -> Error<C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C: Debug> Debug for Error<C>

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

Formats the value using the given formatter.

impl<C: Offsetable> Display for Error<C>

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

Formats the value using the given formatter.

impl<C: Offsetable + Debug> Error for Error<C>

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.
