Struct AnyRoot 

pub struct AnyRoot { /* private fields */ }

A type-erased root garbage collected reference.

Implementations

impl AnyRoot

pub fn load<T>(&self) -> Option<&T>

where T: Collectable,

Loads a reference to the underlying data. Returns None if T is not the type of the underlying data.

pub fn downcast_root<T>(&self) -> Option<Root<T>>

where T: Collectable,

Returns a Root<T> if the underlying reference points to a T.

pub const fn downcast_ref<T>(&self) -> Ref<T>

where T: Collectable,

Returns a Ref<T>.

This function does not do any type checking. If T is not the correct type, attempting to load the underyling value will fail.

pub fn downcast_checked<T>(&self) -> Option<Ref<T>>

where T: Collectable,

Returns a Ref<T>, if T matches the type of this reference.

pub const fn as_any(&self) -> AnyRef

Returns an untyped “weak” reference to this root.

Trait Implementations

impl Clone for AnyRoot

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Drop for AnyRoot

fn drop(&mut self)

Executes the destructor for this type.

impl<T> From<Root<T>> for AnyRoot

where T: Collectable,

fn from(value: Root<T>) -> Self

Converts to this type from the input type.

impl Hash for AnyRoot

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 Ord for AnyRoot

fn cmp(&self, other: &AnyRoot) -> 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 PartialEq for AnyRoot

fn eq(&self, other: &AnyRoot) -> 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 PartialOrd for AnyRoot

fn partial_cmp(&self, other: &AnyRoot) -> 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.
