Struct Handle 

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

Handle to an artifact.

Implementations

impl<T> Handle<T>

pub fn new( chan: Sender<RefOp>, resolved_load_handle: Arc<ResolvedLoadHandle>, ) -> Self

Creates a new handle with HandleRefType::Strong

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

Trait Implementations

impl<T> ArtifactHandle for Handle<T>

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

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

Returns the load status of the artifact.

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

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

where 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: ?Sized> Clone for Handle<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> Debug for Handle<T>

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

Formats the value using the given formatter.

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

fn deserialize<D>(deserializer: D) -> Result<Handle<T>, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: ?Sized> From<GenericHandle> for Handle<T>

fn from(handle: GenericHandle) -> Self

Converts to this type from the input type.

impl<T: ?Sized> From<Handle<T>> for GenericHandle

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

Converts to this type from the input type.

impl<T: ?Sized> Hash for Handle<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> PartialEq for Handle<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> Serialize for Handle<T>

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: Eq + ?Sized> Eq for Handle<T>
