StructDeclaration

All struct declarations are an instance of this.

extern (C++)
class StructDeclaration : AggregateDeclaration {
FuncDeclarations postblits;
FuncDeclaration postblit;
FuncDeclaration xeq;
FuncDeclaration xcmp;
FuncDeclaration xhash;
extern (C++) __gshared
FuncDeclaration xerreq;
extern (C++) __gshared
FuncDeclaration xerrcmp;
TypeTuple argTypes;
structalign_t alignment;
ThreeState ispod;
}

Members

Functions

determineTypeProperties
void determineTypeProperties()

Compute cached type properties for TypeStruct

hasCopyConstruction
bool hasCopyConstruction()

Determine if struct has copy construction (copy constructor or postblit)

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 ?

pMangleOverride
MangleOverride* pMangleOverride;

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

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

userDtors
DtorDeclarations userDtors;

user-defined destructors (~this()) - mixins can yield multiple ones

aggrDtor
DtorDeclaration aggrDtor;

aggregate destructor calling userDtors and fieldDtor (and base class aggregate dtor for C++ classes)

dtor
DtorDeclaration dtor;

the aggregate destructor exposed as __xdtor alias

tidtor
DtorDeclaration tidtor;

(same as aggrDtor, except for C++ classes with virtual dtor on Windows) +//// aggregate destructor used in TypeInfo (must have extern(D) ABI

fieldDtor
DtorDeclaration fieldDtor;

function destructing (non-inherited) fields

getRTInfo
Expression getRTInfo;

pointer to GC info generated by object.RTInfo(this)

visibility
Visibility visibility;
noDefaultCtor
bool noDefaultCtor;

no default construction

disableNew
bool disableNew;

disallow allocations using new

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.

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[].

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.

sinit
void* sinit;

initializer symbol
