Trait Implementations

impl<T> ArtifactHandle for Handle<T>

fn resolved_load_handle(&self) -> &Arc<ResolvedLoadHandle>

fn load_state<T>(&self, loader: &T) -> LoadState

where T: LoadStateProvider,

Returns the load status of the artifact.

fn artifact_id<T>(&self, loader: &T) -> ArtifactId

where T: LoadStateProvider,

fn artifact<'a, T, S>(&self, storage: &'a S) -> Option<&'a T>

where S: TypedArtifactStorage<T>, Self: Sized,

Returns an immutable reference to the artifact if it is committed.

fn downgrade(&self) -> WeakHandle

Downgrades this handle into a WeakHandle.

fn load_handle(&self) -> LoadHandle

Returns the LoadHandle of this artifact handle.

fn direct_load_handle(&self) -> LoadHandle

impl<T> Clone for Handle<T>

where T: ?Sized,

fn clone(&self) -> Handle<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Handle<T>

where T: ?Sized,

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Handle<T>

fn deserialize<D>( deserializer: D, ) -> Result<Handle<T>, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<GenericHandle> for Handle<T>

where T: ?Sized,

fn from(handle: GenericHandle) -> Handle<T>

Converts to this type from the input type.

impl<T> Hash for Handle<T>

where T: ?Sized,

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> PartialEq for Handle<T>

where T: ?Sized,

fn eq(&self, other: &Handle<T>) -> 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> Serialize for Handle<T>

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> Eq for Handle<T>

where T: Eq + ?Sized,
