Validation error for contract metadata.

Variants

EmptySchemaRef

A schema reference was empty or whitespace-only.

DuplicatePortContract

A node contract duplicated the same port identifier.

Fields

node_id: NodeId

Node whose contract is invalid.

port_id: PortId

Duplicated port identifier.

UnknownWorkflowNode

A contract referenced a workflow node that does not exist.

Fields

node_id: NodeId

Missing node identifier.

UnknownWorkflowPort

A contract referenced a port that does not exist on the workflow node.

Fields

node_id: NodeId

Node identifier.

port_id: PortId

Port identifier.

direction: PortDirection

Direction declared by the contract.

PortDirectionMismatch

A contract declared a port with a different direction than the workflow.

Fields

node_id: NodeId

Node identifier.

port_id: PortId

Port identifier.

workflow: PortDirection

Direction declared by the workflow.

contract: PortDirection

Direction declared by the contract.

MissingCapabilityDescriptor

A contract referenced a node with no matching capability descriptor.

Fields

node_id: NodeId

Node identifier.

SchemaMismatch

A contract declared a schema mismatch on a workflow edge.

Fields

edge_index: usize

Zero-based edge index.

source_node_id: NodeId

Source node identifier.

source_port_id: PortId

Source port identifier.

target_node_id: NodeId

Target node identifier.

target_port_id: PortId

Target port identifier.

Capability

Capability validation failed.

Fields

error: CapabilityValidationError

Underlying capability validation error.

Trait Implementations

impl Clone for ContractValidationError

fn clone(&self) -> ContractValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractValidationError

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

Formats the value using the given formatter.

impl Display for ContractValidationError

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

Formats the value using the given formatter.

impl Error for ContractValidationError

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<CapabilityValidationError> for ContractValidationError

fn from(error: CapabilityValidationError) -> Self

Converts to this type from the input type.

impl PartialEq for ContractValidationError

fn eq(&self, other: &ContractValidationError) -> 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.

impl Eq for ContractValidationError
