Struct AnyBufferKey 

pub struct AnyBufferKey { /* private fields */ }

Similar to a BufferKey except it can be used for any buffer without knowing the buffer’s message type at compile time.

This can key be used with a World to directly view or manipulate the contents of a buffer through the AnyBufferWorldAccess interface.

Implementations

impl AnyBufferKey

pub fn downcast_for_message<Message: 'static>( self, ) -> Option<BufferKey<Message>>

Downcast this into a concrete BufferKey for the specified message type.

To downcast to a specialized kind of key, use Self::downcast_buffer_key instead.

pub fn downcast_buffer_key<KeyType: 'static>(self) -> Option<KeyType>

Downcast this into a different special buffer key representation, such as a JsonBufferKey.

pub fn id(&self) -> Entity

The buffer ID of this key.

pub fn session(&self) -> Entity

The session that this key belongs to.

Trait Implementations

impl Accessor for AnyBufferKey

type Buffers = AnyBuffer

fn try_listen_from<'w, 's, 'a, 'b>( buffers: &BufferMap, builder: &'b mut Builder<'w, 's, 'a>, ) -> Result<Chain<'w, 's, 'a, 'b, Self>, IncompatibleLayout>

fn try_buffer_access<T: 'static + Send + Sync>( buffers: &BufferMap, builder: &mut Builder<'_, '_, '_>, ) -> Result<Node<T, (T, Self)>, IncompatibleLayout>

impl BufferKeyLifecycle for AnyBufferKey

type TargetBuffer = AnyBuffer

What kind of buffer this key can unlock.

fn create_key(buffer: &AnyBuffer, builder: &BufferKeyBuilder) -> Self

Create a new key of this type.

fn is_in_use(&self) -> bool

Check if the key is currently in use.

fn deep_clone(&self) -> Self

Create a deep clone of the key. The usage tracking of the clone will be unrelated to the usage tracking of the original.

impl Clone for AnyBufferKey

fn clone(&self) -> AnyBufferKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnyBufferKey

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

Formats the value using the given formatter.

impl<T: 'static + Send + Sync + Any> From<BufferKey<T>> for AnyBufferKey

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

Converts to this type from the input type.
