Struct BoxedError

pub struct BoxedError {
    inner: Box<dyn ErrorExt + Send + Sync>,
}

An opaque boxed error based on errors that implement ErrorExt trait.

Fields

inner: Box<dyn ErrorExt + Send + Sync>

Implementations

impl BoxedError

pub fn new<E: ErrorExt + Send + Sync + 'static>(err: E) -> Self

pub fn into_inner(self) -> Box<dyn ErrorExt + Send + Sync>

Trait Implementations

impl Debug for BoxedError

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

Formats the value using the given formatter.

impl Display for BoxedError

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

Formats the value using the given formatter.

impl Error for BoxedError

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 ErrorCompat for BoxedError

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

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl ErrorExt for BoxedError

fn status_code(&self) -> StatusCode

Map this error to StatusCode.

fn as_any(&self) -> &dyn Any

Returns the error as Any so that it can be downcast to a specific implementation.

fn output_msg(&self) -> String

where Self: Sized,

fn root_cause(&self) -> Option<&dyn Error>

where Self: Sized,

Find out root level error for nested error

impl StackError for BoxedError

fn debug_fmt(&self, layer: usize, buf: &mut Vec<String>)

fn next(&self) -> Option<&dyn StackError>

fn last(&self) -> &dyn StackError

where Self: Sized,

fn transparent(&self) -> bool

Indicates whether this error is “transparent”, that it delegates its “display” and “source” to the underlying error. Could be useful when you are just wrapping some external error, AND can not or would not provide meaningful contextual info. For example, the DataFusionError.
