2026-10-02: Why a pipeline could not be required, declared or matched.

Variants

Required

2026-10-02: The policy or the circuit does not state what a step needs.

Fields

node: String

2026-10-02: Node id.

op: String

2026-10-02: Its op.

detail: String

2026-10-02: What is missing or contradictory.

Undeclared

2026-10-02: A group’s kernels are in no family, so their pipeline is undeclared.

Fields

node: String

2026-10-02: Node id.

op: String

2026-10-02: Its op.

kernels: String

2026-10-02: The group’s kernels or emitter.

Declared

2026-10-02: A family’s declaration cannot be resolved for a node.

Fields

node: String

2026-10-02: Node id.

op: String

2026-10-02: Its op.

family: String

2026-10-02: Family id.

detail: String

2026-10-02: Why.

Mismatch(Vec<Mismatch>)

2026-10-02: Kernels declare another pipeline than a plan requires, one entry per node.

Trait Implementations

impl Clone for PipelineError

fn clone(&self) -> PipelineError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PipelineError

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

Formats the value using the given formatter.

impl Display for PipelineError

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

Formats the value using the given formatter.

impl Error for PipelineError

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 From<PipelineError> for LoadError

fn from(source: PipelineError) -> Self

Converts to this type from the input type.

impl PartialEq for PipelineError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
