Struct UnsupportedTask 

pub struct UnsupportedTask {
    pub engine: &'static str,
    pub kind: &'static str,
}

Typed “this engine cannot serve this task kind” error.

Engines return this (instead of an ad-hoc string) when a task of a kind they don’t implement reaches their dispatch, so the session classifies the failure as non-retryable via a downcast (runtime::is_unsupported_kind) instead of sniffing message text. The rendered message keeps the legacy <engine> engine cannot serve <kind> tasks shape operators already grep for.

Fields

engine: &'static str

kind: &'static str

Implementations

impl UnsupportedTask

pub fn new(engine: &'static str, kind: TaskKind) -> Self

Trait Implementations

impl Debug for UnsupportedTask

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

Formats the value using the given formatter.

impl Display for UnsupportedTask

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

Formats the value using the given formatter.

impl Error for UnsupportedTask

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.
