Diagnostics

AspectGenerator diagnostics are intended to report user mistakes before generated code fails to compile.

Existing Diagnostics

• AG0001: OnCall aspect must be last when the aspect is applied directly.
• AG0002: OnCall aspect must be last when the aspect is inferred from method metadata.
• AG0003: invocation cannot be intercepted by the compiler.
• AG0004: generated interceptor namespace is not listed in InterceptorsNamespaces.

Planned Hook Contract Diagnostics

• AG0101: hook method not found.
• AG0102: hook method must be static.
• AG0103: invalid hook parameter type.
• AG0104: invalid hook return type.
• AG0105: OnCall signature mismatch.
• AG0106: UseInterceptData=true requires ref InterceptData<T>.
• AG0107: async hook requires a supported async target.

Planned InterceptMethods Diagnostics

• unmatched method display string;
• ambiguous match;
• alias-sensitive match requiring a more precise spelling.
