Struct EngineError 

pub struct EngineError { /* private fields */ }

Error type exposed by the typed engine boundary.

Implementations

impl EngineError

pub fn cancelled(stage: &str) -> Self

Create the error an analysis returns when its caller cancelled it.

stage names the pipeline boundary the run stopped at, so a caller can tell how far the analysis got before it was stopped.

pub const fn is_cancelled(&self) -> bool

Whether this error reports a caller-requested cancellation rather than a failed analysis.

pub fn message(&self) -> &str

User-facing error message from the backend.

impl Eq for EngineError

impl Error for EngineError

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 PartialEq for EngineError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
