Struct InterceptorReceiverEligibility

Describes whether the receiver of a call can or must be mapped to the this of the generated interceptor method, that is, whether ReceiverMapping can or must be This. The ReceiverEligibility property gives it.

[CompileTime]
public readonly struct InterceptorReceiverEligibility : IEquatable<InterceptorReceiverEligibility>

Remarks

The properties are nested: IsThisRequired implies IsThisEligibleForAllSites, which implies IsThisEligible. The default value of the structure has all the properties false: the receiver cannot be mapped to this.

The sites of a group are the call sites that are intercepted with the same template, in the same placement type, for the same intercepted method. The constructions of a generic type and of a generic method are the same type and the same method. A call site that cannot be intercepted is not part of a group.

Properties

Name	Description
IsThisEligible	Gets a value indicating whether the receiver of the call can be mapped to `this` at the current call site. This describes the conditions.
IsThisEligibleForAllSites	Gets a value indicating whether the receiver can be mapped to `this` at every call site of the group of the current call site. When the delegates map the receiver to `this` at every site of the group, the sites can share one generated instance method.
IsThisRequired	Gets a value indicating whether the receiver must be mapped to `this`, because the intercepted method is a protected method of a base type of the calling type, which a static method cannot call through a receiver parameter. The receiver mapping is then This and cannot change.
