Struct BoxError 

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

Used to encapsulate opaque dyn core::error::Error types.

This wrapper allows you to work with arbitrary error types in a uniform way while preserving the original error information.

Implementations

impl BoxError

pub fn new<E>(err: E) -> Report<Self>

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

Create a new BoxError report from any error type.

This method boxes the error and wraps it in a Report.

pub fn from(err: Box<dyn Error + Send + Sync + 'static>) -> Report<Self>

Create a BoxError report from an already-boxed error.

Trait Implementations

impl Debug for BoxError

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

Formats the value using the given formatter.

impl Display for BoxError

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

Formats the value using the given formatter.

impl Error for BoxError

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.
