Struct ChainedError 

pub struct ChainedError { /* private fields */ }

A generic error which represents a linked-list of errors and exposes it with source(). It’s meant to be the target of a conversion of any Exn error tree.

It’s useful for inter-op with other error handling crates like anyhow which offer simplified access to the error chain, and thus is expected to be wrapped in one of their types intead of being used directly.

Trait Implementations

impl Debug for ChainedError

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

Formats the value using the given formatter.

impl Display for ChainedError

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

Formats the value using the given formatter.

impl Error for ChainedError

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<Exn<E>> for ChainedError

where E: Error + Send + Sync + 'static,

fn from(err: Exn<E>) -> Self

Converts to this type from the input type.
