Error while building the HUGR.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidHUGR(ValidationError<Node>)

The constructed HUGR is invalid.

SignatureError(SignatureError)

SignatureError in trying to construct a node (differs from ValidationError::SignatureError in that we could not construct a node to report about)

BadConstant(ConstTypeError)

Tried to add a malformed Const

EntryBuiltError(Node)

CFG can only have one entry.

BasicBlockTooComplex

We don’t allow creating BasicBlockBuilder<Hugr>s when the sum-rows are not homogeneous. Use a CFGBuilder and create a valid graph instead.

UnexpectedType

Node was expected to have a certain type but was found to not.

Fields

node: Node

Index of node where error occurred.

op_desc: &'static str

Description of expected node.

ConditionalError(ConditionalBuildError)

Error building Conditional node

NodeNotFound

Node not found in Hugr

Fields

node: Node

Missing node

HugrInsertionError(NodeLinkingError<Node, Node>)

From Dataflow::add_link_hugr_by_node_with_wires

HugrViewInsertionError(String)

From Dataflow::add_link_view_by_node_with_wires. Note that because the type of node in the NodeLinkingError depends upon the view being inserted, we convert the error to a string here.

WireNotFound(Wire)

Wire not found in Hugr

CircuitError(CircuitBuildError)

Error in CircuitBuilder

OutputWiring

Invalid wires when setting outputs

Fields

container_op: Box<OpType>

container_node: Node

error: BuilderWiringError

OperationWiring

Invalid input wires to a new operation

The internal error message already contains the node index.

Fields

op: Box<OpType>

error: BuilderWiringError

ExtensionOp(OpLoadError)

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> BuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

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<CircuitBuildError> for BuildError

fn from(source: CircuitBuildError) -> Self

Converts to this type from the input type.

impl From<ConstTypeError> for BuildError

fn from(source: ConstTypeError) -> Self

Converts to this type from the input type.

impl From<NodeLinkingError> for BuildError

fn from(source: NodeLinkingError<Node, Node>) -> Self

Converts to this type from the input type.

impl From<OpLoadError> for BuildError

fn from(source: OpLoadError) -> Self

Converts to this type from the input type.

impl From<SignatureError> for BuildError

fn from(source: SignatureError) -> Self

Converts to this type from the input type.

impl From<ValidationError<Node>> for BuildError

fn from(source: ValidationError<Node>) -> Self

Converts to this type from the input type.

impl PartialEq for BuildError

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