Functions

argTypes int argTypes(TypeInfo arg1, TypeInfo arg2): Return internal info on arguments fitting into 8byte. * See X86-64 ABI 3.2.3
compare int compare(void* p1, void* p2): Compares two instances for <, ==, or >.
equals equals_t equals(void* p1, void* p2): Compares two instances for equality.
flags uint flags(): Get flags for type: 1 means GC should scan for pointers
getHash hash_t getHash(void* p): Returns a hash of the instance of a type.
init void[] init(): Return default initializer, null if default initialize to 0
next TypeInfo next(): Get TypeInfo for 'next' type, as defined by what kind of type this is, null if none.
offTi OffsetTypeInfo[] offTi(): Get type information on the contents of the type; null if not available
opCmp int opCmp(Object o): Undocumented in source. Be warned that the author may not have intended to support it.
opEquals equals_t opEquals(Object o): Undocumented in source. Be warned that the author may not have intended to support it.
pointermap PointerMap pointermap(): Get a pointer to PointerMap; used for GC scanning
swap void swap(void* p1, void* p2): Swaps two instances of the type.
talign size_t talign(): Return alignment of type
toHash hash_t toHash(): Undocumented in source. Be warned that the author may not have intended to support it.
tsize size_t tsize(): Returns size of the type.
