Functions

func GetArrayElem

func GetArrayElem[T any](array unsafe.Pointer, index int, elemSize uintptr) T

GetArrayElem returns an element by index from the array referenced by an unsafe pointer

func GetArrayElemRef

func GetArrayElemRef(array unsafe.Pointer, index int, elemSize uintptr) unsafe.Pointer

GetArrayElemRef returns an element's pointer by index from the array referenced by an unsafe pointer

func GetArrayPointer

func GetArrayPointer[T any](elements []T) unsafe.Pointer

GetArrayPointer retrieves the pointer of a slice underlying array

func GetLen

func GetLen[T any](elements []T) int

GetLen returns the length of elements

func GetSliceHeader

func GetSliceHeader[T any](elements []T) *reflect.SliceHeader

GetSliceHeader retrieves the SliceHeader of elements

func GetSliceHeaderByRef

func GetSliceHeaderByRef(elements unsafe.Pointer) *reflect.SliceHeader

GetSliceHeaderByRef retrieves the SliceHeader of elements by an unsafe pointer

func GetTypeSize

func GetTypeSize[T any]() uintptr

GetTypeSize retrieves size of a type T

func InHeap

func InHeap[T any](t *T) bool

InHeap is generic link to runtime.inheap
