Struct ByteFn

pub(crate) struct ByteFn(GcHeap<ByteFnPrototype>);

A function implemented in lisp. Note that all functions are byte compiled, so this contains the byte-code representation of the function.

Tuple Fields

0: GcHeap<ByteFnPrototype>

Trait Implementations

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

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

impl Markable for ByteFn

type Value = NonNull<ByteFn>

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

impl PartialEq for ByteFn

fn eq(&self, other: &ByteFn) -> 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 ByteFn

type Target = RootedByteFn

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

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

impl TaggedPtr for &ByteFn

const TAG: Tag = Tag::ByteFn

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

type Ptr = ByteFn

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 ByteFn

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

impl<'ob> TryFrom<Gc<ObjectType<'ob>>> for &'ob ByteFn

type Error = TypeError

The type returned in the event of a conversion error.

fn try_from(obj: Gc<ObjectType<'ob>>) -> Result<Self, Self::Error>

Performs the conversion.

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

type Out = &'new ByteFn

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

impl<'ob> From<&'ob ByteFn> for Gc<FunctionType<'ob>>

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

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

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

Converts to this type from the input type.

impl Debug for ByteFn

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

Formats the value using the given formatter.

impl Display for ByteFn

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

Formats the value using the given formatter.

impl Deref for ByteFn

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

The resulting type after dereferencing.

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