Struct gluon_vm::gc::GcPtr

pub struct GcPtr<T: ?Sized> { /* private fields */ }

A pointer to a garbage collected value.

It is only safe to access data through a GcPtr if the value is rooted (stored in a place where the garbage collector will find it during the mark phase).

Implementations

impl<T: ?Sized> GcPtr<T>

pub unsafe fn as_mut(&mut self) -> &mut T

Unsafe as it is up to the caller to ensure that this pointer is not referenced somewhere else

pub unsafe fn from_raw(ptr: *const T) -> GcPtr<T>

Unsafe as ptr must have been allocted by this garbage collector

impl<'a, T: Traverseable + Send + Sync + 'a> GcPtr<T>

pub fn as_traverseable(self) -> GcPtr<dyn Traverseable + Send + Sync + 'a>

Coerces self to a Traverseable trait object

impl GcPtr<str>

pub fn as_traverseable_string(self) -> GcPtr<dyn Traverseable + Send + Sync>

Coerces self to a Traverseable trait object

Trait Implementations

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

Formats the value using the given formatter.

impl<T: ?Sized> Deref for GcPtr<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: ?Sized + Hash> Hash for GcPtr<T>

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

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<T: ?Sized + Ord> Ord for GcPtr<T>

fn cmp(&self, other: &GcPtr<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<T: ?Sized + PartialEq> PartialEq<GcPtr<T>> for GcPtr<T>

fn eq(&self, other: &GcPtr<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
