An error that can occur when expanding a gate that has a sequence gate definition.

NonFixedQubitArgument(Qubit)

GateModifiersUnsupported(Vec<GateModifier>)

InvalidGateSequenceElementQubit(Qubit)

Gate sequence element is a gate application where the formal qubit must be an argument. Note, this error should never occur because gate sequence elements are validated in DefGateSequence::try_new. We still prefer returning an error to panicking.

UndefinedGateSequenceElementQubit(String)

Qubit variable in gate sequence is undefined. Note, this error should never occur because gate sequence elements are validated in DefGateSequence::try_new. We still prefer returning an error to panicking.

Trait Implementations

impl Clone for DefGateSequenceExpansionError

fn clone(&self) -> DefGateSequenceExpansionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DefGateSequenceExpansionError

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

Formats the value using the given formatter.

impl Display for DefGateSequenceExpansionError

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

Formats the value using the given formatter.

impl Error for DefGateSequenceExpansionError

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<DefGateSequenceExpansionError> for ProgramError

fn from(source: DefGateSequenceExpansionError) -> Self

Converts to this type from the input type.

impl PartialEq for DefGateSequenceExpansionError

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