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

Returns:

FuncDeclaration of toString() if found, null if not

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

class StructDeclaration: dmd.aggregate.AggregateDeclaration;

All struct declarations are an instance of this.

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.

Returns:

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

final bool isPOD();

Determine if struct is POD (Plain Old Data).

POD is defined as:

not nested
no postblits, destructors, or assignment operators
no ref fields or fields that are themselves non-POD

The idea being these are compatible with C structs.

Returns:

true if struct is POD

class UnionDeclaration: dmd.dstruct.StructDeclaration;

Unions are a variation on structs.
