Public Functions

inline ConstraintContext()

Construct an empty root.

inline ConstraintContext(ConstraintContext parent, int64_t parent_local_prefix)

Construct a child capturing [0, parent_local_prefix) of its parent’s local entries. Later parent appends do not enter this child’s effective constraints.

Parameters:

• parent – Context supplying inherited constraints.

• parent_local_prefix – Number of parent-local entries to capture, between zero and parent->LocalSize(), inclusive.

Throws:

ffi::Error – If the prefix is outside that range.

inline explicit ConstraintContext(ffi::ObjectPtr<ConstraintContextObj> node)

Adopt a reference to a non-null context object.
