Functions

fit bool fit(Loc loc, Scope* sc, Expressions* elements, Type stype): Fit elements[] to the corresponding types of the struct's fields.
hasRegularCtor bool hasRegularCtor(bool checkDisabled): Verifies whether the struct declaration has a constructor that is not a copy constructor. Optionally, it can check whether the struct declaration has a regular constructor, that is not disabled.
isPOD bool isPOD(): Determine if struct is POD (Plain Old Data).

Inherited Members

From AggregateDeclaration

type Type type;
storage_class StorageClass storage_class;
structsize uint structsize;: size of struct
alignsize uint alignsize;: size of struct for alignment purposes
fields VarDeclarations fields;: VarDeclaration fields
deferred Dsymbol deferred;: any deferred semantic2() or semantic3() symbol
classKind ClassKind classKind;: specifies whether this is a D, C++, Objective-C or anonymous struct/class/interface
cppmangle CPPMANGLE cppmangle;: Specify whether to mangle the aggregate as a class or a struct This information is used by the MSVC mangler Only valid for class and struct. TODO: Merge with ClassKind ?
mangleOverride MangleOverride* mangleOverride;: overridden symbol with pragma(mangle, "...") if not null
enclosing Dsymbol enclosing;: !=null if is nested pointing to the dsymbol that directly enclosing it. 1. The function that enclosing it (nested struct and class) 2. The class that enclosing it (nested class only) 3. If enclosing aggregate is template, its enclosing dsymbol.
vthis VarDeclaration vthis;: 'this' parameter if this aggregate is nested
vthis2 VarDeclaration vthis2;: 'this' parameter if this aggregate is a template and is nested
invs FuncDeclarations invs;: Array of invariants
inv FuncDeclaration inv;: Merged invariant calling all members of invs
aggNew NewDeclaration aggNew;: allocator
ctor Dsymbol ctor;: CtorDeclaration or TemplateDeclaration
defaultCtor CtorDeclaration defaultCtor;: default constructor - should have no arguments, because it would be stored in TypeInfo_Class.defaultConstructor
aliasthis AliasThis aliasthis;: forward unresolved lookups to aliasthis
dtors DtorDeclarations dtors;: Array of destructors
dtor DtorDeclaration dtor;: aggregate destructor calling dtors and member constructors
primaryDtor DtorDeclaration primaryDtor;: non-deleting C++ destructor, same as dtor for D
tidtor DtorDeclaration tidtor;: aggregate destructor used in TypeInfo (must have extern(D) ABI)
fieldDtor FuncDeclaration fieldDtor;: aggregate destructor for just the fields
getRTInfo Expression getRTInfo;: pointer to GC info generated by object.RTInfo(this)
visibility Visibility visibility;
noDefaultCtor bool noDefaultCtor;: no default construction
sizeok Sizeok sizeok;: set when structsize contains valid data
newScope Scope* newScope(Scope* sc): Create a new scope from sc. semantic, semantic2 and semantic3 will use this for aggregate members.
determineFields bool determineFields(): Find all instance fields, then push them into fields.
nonHiddenFields size_t nonHiddenFields()
determineSize bool determineSize(Loc loc): Collect all instance fields, then determine instance size.
checkOverlappedFields bool checkOverlappedFields(): Calculate fieldi.overlapped and overlapUnsafe, and check that all of explicit field initializers have unique memory space on instance.
fill bool fill(Loc loc, Expressions* elements, bool ctorinit): Fill out remainder of elements[] with default initializers for fields[].
alignmember void alignmember(structalign_t alignment, uint size, uint* poffset): Do byte or word alignment as necessary. Align sizes of 0, as we may not know array sizes yet.
placeField uint placeField(uint* nextoffset, uint memsize, uint memalignsize, structalign_t alignment, uint* paggsize, uint* paggalignsize, bool isunion): Place a member (mem) into an aggregate (agg), which can be a struct, union or class
setDeprecated void setDeprecated(): Flag this aggregate as deprecated
isNested bool isNested(): Returns true if there's an extra member which is the 'this' pointer to the enclosing context (enclosing aggregate or function)
searchCtor Dsymbol searchCtor(): Look for constructor declaration.
stag Symbol* stag;: tag symbol for debug data
sinit Symbol* sinit;: initializer symbol
