Trait Implementations

impl<'gc> Clone for AnyUserData<'gc>

fn clone(&self) -> AnyUserData<'gc>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'gc> Collect for AnyUserData<'gc>

fn needs_trace() -> bool

As an optimization, if this type can never hold a Gc pointer and trace is unnecessary to call, you may implement this method and return false. The default implementation returns true, signaling that Collect::trace must be called.

fn trace(&self, cc: &Collection)

Must call Collect::trace on all held Gc pointers. If this type holds inner types that implement Collect, a valid implementation would simply call Collect::trace on all the held values to ensure this.

impl<'gc> Debug for AnyUserData<'gc>

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

Formats the value using the given formatter.

impl<'gc> Hash for AnyUserData<'gc>

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<'gc> PartialEq for AnyUserData<'gc>

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<'gc> Stashable<'gc> for AnyUserData<'gc>

type Stashed = StaticUserData

fn stash(self, roots: &DynamicRootSet<'gc>, mc: &Mutation<'gc>) -> Self::Stashed

impl<'gc> Copy for AnyUserData<'gc>

impl<'gc> Eq for AnyUserData<'gc>
