Enum PointerObj

pub enum PointerObj {
    Released,
    UpVal(UpValue),
    Struct(Rc<(RefCell<StructObj>, RCount)>, GosMetadata),
    Array(Rc<(ArrayObj, RCount)>, GosMetadata),
    Slice(Rc<(SliceObj, RCount)>, GosMetadata),
    Map(Rc<(MapObj, RCount)>, GosMetadata),
    SliceMember(Rc<(SliceObj, RCount)>, OpIndex),
    StructField(Rc<(RefCell<StructObj>, RCount)>, OpIndex),
    PkgMember(PackageKey, OpIndex),
}

Logically there are 4 types of pointers, they point to:

• local
• slice member
• struct field
• package member and for pointers to locals, the default way of handling it is to use “UpValue” (PointerObj::UpVal). Struct/Map/Slice are optimizations for this type, when the pointee has a “real” pointer

Trait Implementations

impl Clone for PointerObj

fn clone(&self) -> PointerObj

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PointerObj

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PointerObj

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for PointerObj

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PointerObj

fn eq(&self, other: &PointerObj) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
