Call

Call#

class hugr.ops.Call(signature: tys.PolyFuncType, instantiation: tys.FunctionType | None = None, type_args: Sequence[tys.TypeArg] | None = None)[source]#

Bases: _CallOrLoad, Op

Call a function inside a dataflow graph. Connects to FuncDefn or FuncDecl operations.

Parameters:

  • signature – Polymorphic function signature.

  • instantiation – Concrete function signature. Defaults to None.

  • type_args – Type arguments for polymorphic function. Defaults to None.

Raises:

NoConcreteFunc – If the signature is polymorphic and no instantiation is provided.

Methods

name

Name of the operation.

port_kind

Get the kind of the given port.

Attributes

num_out

The number of output ports for this operation.

signature

polymorphic function signature

instantiation

concrete function signature

type_args

instantiation: FunctionType#

concrete function signature

name() → str[source]#

Name of the operation.

property num_out: int#

The number of output ports for this operation.

Example

>>> op = Const(val.TRUE)
>>> op.num_out
1
port_kind(port: InPort | OutPort) → ValueKind | ConstKind | FunctionKind | CFKind | OrderKind[source]#

Get the kind of the given port.

Example

>>> op = Const(val.TRUE)
>>> op.port_kind(OutPort(Node(0), 0))
ConstKind(Bool)
