Struct ErrorContext 

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

Enhanced error wrapper with context

Implementations

impl<E> ErrorContext<E>

pub fn new(error: E, context: OperationContext) -> Self

Create a new error context

pub fn with_location(self, location: ErrorLocation) -> Self

Add location information

pub fn with_source<S>(self, source: S) -> Self

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

Add a parent error to the chain

pub fn with_suggestion(self, suggestion: &str) -> Self

Add a recovery suggestion

pub fn error(&self) -> &E

Get the underlying error

pub fn context(&self) -> &OperationContext

Get the operation context

pub fn location(&self) -> Option<&ErrorLocation>

Get the error location

pub fn chain(&self) -> &[Box<dyn Error + Send + Sync>]

Get the error chain

pub fn recovery_suggestions(&self) -> &[String]

Get recovery suggestions

pub fn into_inner(self) -> E

Consume the wrapper and return the underlying error

Trait Implementations

impl<E: Debug> Debug for ErrorContext<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for ErrorContext<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Error for ErrorContext<E>

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.
