Implementations

impl Record

fn display_walk( &self, f: &mut Formatter<'_>, seen: &mut HashSet<*const u8>, ) -> Result

Methods from Deref<Target = <GcHeap<LispVecInner> as std_ops_Deref>::Target>

const NULL: *mut u8 = {0x0 as *mut u8}

const EMTPTY: AtomicPtr<u8> = _

fn header(&self) -> &GcHeader

pub(in core) fn forward( &self, fwd_ptr: NonNull<u8>, )

pub(in core) fn allocation_state( &self, ) -> AllocState

fn is_marked(&self) -> bool

Trait Implementations

impl<'new> CloneIn<'new, &'new Record> for Record

fn clone_in<const C: bool>(&self, bk: &'new Block<C>) -> Gc<&'new Self>

impl Markable for Record

type Value = NonNull<Record>

fn move_value(&self, to_space: &Bump) -> Option<(Self::Value, bool)>

impl PartialEq for Record

fn eq(&self, other: &Record) -> 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.

impl RootedDeref for Record

type Target = RootedRecord

fn rooted_deref(rooted: &Rt<Self>) -> &Self::Target

fn rooted_derefmut(rooted: &mut Rt<Self>) -> &mut Self::Target

impl TaggedPtr for &Record

const TAG: Tag = Tag::Record

Tag value. This is only applicable to base values. Use Int for sum types.

type Ptr = LispVec

The type of object being pointed to. This will be different for all implementors.

unsafe fn from_obj_ptr(ptr: *const u8) -> Self

Given an untyped pointer, reinterpret to self.

fn get_ptr(self) -> *const Self::Ptr

Get the underlying pointer.

unsafe fn tag_ptr(ptr: *const Self::Ptr) -> Gc<Self>

Given a pointer to Ptr return a Tagged pointer.

fn untag(val: Gc<Self>) -> Self

Remove the tag from the Gc<T> and return the inner type. If it is base type then it will only have a single possible value and can be untagged without checks, but sum types need to create all values they can hold. We use tagged base types to let us reinterpret bits without actually modify them.

fn tag(self) -> Gc<Self>

Given the type, return a tagged version of it. When using a sum type or an immediate value like i64, we override this method to set the proper tag.

impl Trace for Record

fn trace(&self, state: &mut GcState)

impl<'old, 'new> WithLifetime<'new> for &'old Record

type Out = &'new Record

unsafe fn with_lifetime(self) -> Self::Out

impl<'ob> From<&'ob Record> for Gc<ObjectType<'ob>>

fn from(x: &'ob Record) -> Self

Converts to this type from the input type.

impl Display for Record

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

Formats the value using the given formatter.

impl Deref for Record

type Target = <GcHeap<LispVecInner> as Deref>::Target

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
