Expand description
Constraint system for testing purposes.
Implementations

type Root = Self
type Root = Self
Represents the type of the “root” of this constraint system so that nested namespaces can minimize indirection. Read more
Allocate a private variable in the constraint system. The provided function is used to
determine the assignment of the variable. The given annotation
function is invoked
in testing contexts in order to derive a unique name for this variable in the current
namespace. Read more

Create a new (sub)namespace and enter into it. Not intended
for downstream use; use namespace
instead. Read more
Exit out of the existing namespace. Not intended for
downstream use; use namespace
instead. Read more
Gets the “root” constraint system, bypassing the namespacing.
Not intended for downstream use; use namespace
instead. Read more
Begin a namespace for this constraint system.
Most implementations of ConstraintSystem are not ‘extensible’: they won’t implement a specialized
version of extend
and should therefore also keep the default implementation of is_extensible
so callers which optionally make use of extend
can know to avoid relying on it when unimplemented. Read more
Extend concatenates thew other
constraint systems to the receiver, modifying the receiver, whose
inputs, allocated variables, and constraints will precede those of the other
constraint system.
The primary use case for this is parallel synthesis of circuits which can be decomposed into
entirely independent sub-circuits. Each can be synthesized in its own thread, then the
original ConstraintSystem
can be extended with each, in the same order they would have
been synthesized sequentially. Read more
