search_toString

Declaration

FuncDeclaration search_toString(StructDeclaration sd);

Search sd for a member function of the form: extern (D) string toString();

Parameters

StructDeclaration sd

struct declaration to search

Return Value

FuncDeclaration of toString() if found, null if not
semanticTypeInfo

Declaration

void semanticTypeInfo(Scope* sc, Type t);

Request additional semantic analysis for TypeInfo generation.

Parameters

Scope* sc

context

Type t

type that TypeInfo is being generated for

StructDeclaration

Declaration

class StructDeclaration: dmd.aggregate.AggregateDeclaration;

All struct declarations are an instance of this.

fit

Declaration

final bool fit(ref const Loc loc, Scope* sc, Expressions* elements, Type stype);

Fit elements[] to the corresponding types of the struct's fields.

Parameters

`Loc loc`	location to use for error messages
`Scope* sc`	context
`Expressions* elements`	explicit arguments used to construct object
`Type stype`	the constructed object type.

Return Value

false if any errors occur, otherwise true and elements[] are rewritten for the output.

isPOD

Declaration

final bool isPOD();
Determine if struct is POD (Plain Old Data).
Discussion

POD is defined as:
1. not nested
2. no postblits, destructors, or assignment operators
3. no ref fields or fields that are themselves non-POD
The idea being these are compatible with C structs.
Return Value

true if struct is POD

UnionDeclaration

Declaration

class UnionDeclaration: dmd.dstruct.StructDeclaration;

Unions are a variation on structs.
