AnyType

AnyType

AnyType represents the type of runtime type information.

Specifications

Type	Size	Memory Management Model	File
AnyType	32 bytes	None	N/A

Definition

struct AnyType (kind AnyTypeKind, name *ubyte, is_alias bool, size usize)

Fields

Name	Type	Description
kind	AnyTypeKind	What kind of type
name	*ubyte	Human readable name of the type
is_alias	bool	Whether the type is an alias
size	usize	Size of the type in bytes

As a Value Header

Most *AnyType values don't directly refer to an AnyType, but rather one of the types like AnyType such as AnyStructType or AnyPtrType. Which kind of type it is can be determined by examining the kind of AnyType.

More detailed overlapping structs include:

• AnyPtrType
• AnyStructType
• AnyUnionType
• AnyFuncPtrType
• AnyFixedArrayType

Usage in __types__

When runtime type information is enabled, the compiler will include the global variables __types__ and __types_length__:

__types__ **AnyType
__types_length__ usize

These contain runtime type information for every type used in the program.
