Module dmd.clone

Builds struct member functions if needed and not defined by the user. Includes opEquals, opAssign, post blit, copy constructor and destructor.




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.
