Code to gather up constraints. Constraint construction and representation

The second pass over the AST determines the set of constraints. We walk the set of items and, for each member, generate new constraints.

Structs

  • Constraint
    Declares that the variable decl_id appears in a location with variance variance.
  • ConstraintContext
  • CurrentItem
    To build constraints, we visit one item (type, trait) at a time and look at its contents. So e.g., if we have
