Struct Gc 

pub struct Gc<'b, T: ?Sized>(/* private fields */);

A thin, copyable, garbage collected pointer type.

Implementations

impl<'b, T: Collect> Gc<'b, T>

pub fn new(val: T, mt: &Mutation<'b>) -> Gc<'b, T>

Allocates garbage collected memory on the heap and then places val into it.

This allocates regardless of if T is zero-sized.

If initialization of a more complex type is required, see UniqueGc.

impl<'b> Gc<'b, str>

pub fn from_str(s: &str, mt: &Mutation<'b>) -> Gc<'b, str>

impl<'b, T: ?Sized> Gc<'b, T>

pub fn write(&self) -> &Write<T>

pub fn unlock(&self) -> &T::Unlocked

where T: Unlock,

pub fn as_ptr(&self) -> *mut T

pub fn long_ref(&self) -> &'b T

Returns a reference to the contained value, which lasts for as long as the current view is active.

pub fn downgrade(this: Gc<'b, T>) -> Weak<'b, T>

Trait Implementations

impl<T: ?Sized> Clone for Gc<'_, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized> Collect for Gc<'_, T>

const NEEDS_TRACE: bool = true

fn trace(&self, c: &Collector)

impl<T: Debug + ?Sized> Debug for Gc<'_, T>

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

Formats the value using the given formatter.

impl<T: ?Sized> Deref for Gc<'_, T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: ?Sized + Hash> Hash for Gc<'_, T>

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<T: ?Sized + Ord> Ord for Gc<'_, T>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: ?Sized + PartialEq> PartialEq for Gc<'_, T>

fn eq(&self, other: &Self) -> 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<T: ?Sized + PartialOrd> PartialOrd for Gc<'_, T>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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