Functions

Name	Description
`buildCopyCtor(sd, sc)`	Generates a copy constructor if needCopyCtor() returns true. The generated copy constructor will be of the form: this(ref return scope inout(S) rhs) inout { this.field1 = rhs.field1; this.field2 = rhs.field2; ... }
`buildDtors(ad, sc)`	Create aggregate destructor for struct/class by aggregating all the destructors in userDtors[] with the destructors for all the members. Sets ad's fieldDtor, aggrDtor, dtor and tidtor fields.
`buildInv(ad, sc)`	Create inclusive invariant for struct/class by aggregating all the invariants in invs[].
`buildOpAssign(sd, sc)`	Build opAssign for a `struct`.
`buildOpEquals(sd, sc)`	Build opEquals for struct. const bool opEquals(const S s) { ... }
`buildPostBlit(sd, sc)`	Create inclusive postblit for struct by aggregating all the postblits in postblits[] with the postblits for all the members. Note the close similarity with AggregateDeclaration::buildDtor(), and the ordering changes (runs forward instead of backwards).
`buildXopCmp(sd, sc)`	Build _xopCmp for TypeInfo_Struct int _xopCmp(ref const S p) const { return this.opCmp(p); }
`buildXopEquals(sd, sc)`	Build _xopEquals for TypeInfo_Struct bool _xopEquals(ref const S p) const { return this == p; }
`buildXtoHash(sd, sc)`	Build _xtoHash for non-bitwise hashing static hash_t xtoHash(ref const S p) nothrow @trusted;
`hasIdentityOpAssign(ad, sc)`	Check given aggregate actually has an identity opAssign or not.
`mergeFuncAttrs(s1, f)`	Merge function attributes pure, nothrow, @safe, @nogc, and @disable from f into s1.
`needCopyCtor(sd, hasCpCtor)`	Determine if a copy constructor is needed for struct sd, if the following conditions are met:
`needOpEquals(sd)`	We need an opEquals for the struct if any fields has an opEquals. Generate one if a user-specified one does not exist.
