trait CanBindLocals[R] extends AnyRef

Type class describing how Local binding works for specific data types.

This is needed because asynchronous data types, like Future, that can be waited on, should also clear the modified context after completion.

NOTE: this type class does not work for data types that suspend the execution, like Coeval or Task, because Local is meant to be used in a side effectful way. Instances of this type class can't be implemented for data types like Task, as a technical limitation, because Task would also need a suspended Context evaluation in bindContext.

@implicitNotFound("""Cannot find an implicit value for CanBindLocals[${R}].
If ${R} is the result of a synchronous action, either build an implicit with
CanBindLocals.synchronous or import CanBindLocals.Implicits.synchronousAsDefault."""
