Vttree-constraints->constraints

Get the constraints field from a vttree-constraints.

Signature

(vttree-constraints->constraints x) → constraints

Arguments

x — Guard (vttree-p x).

Returns

constraints — Type (sv::constraintlist-p constraints).

This is an ordinary field accessor created by defprod.
