trait TypeConstraint

[source: scala/TypeConstraint.scala]

trait TypeConstraint
extends Annotation

A marker for annotations that, when applied to a type, should be treated as a constraint on the annotated type. A proper constraint should restrict the type based only on information mentioned within the type. A Scala compiler can use this assumption to rewrite the contents of the constraint as necessary. To contrast, a type annotation whose meaning depends on the context where it is written down is not a proper constrained type, and this marker should not be applied. A Scala compiler will drop such annotations in cases where it would rewrite a type constraint.
