Struct JsonBufferKey 

pub struct JsonBufferKey { /* private fields */ }

Similar to a BufferKey except it can be used for any buffer that supports serialization and deserialization without knowing the buffer’s specific 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 JsonBufferWorldAccess interface.

Implementations

impl JsonBufferKey

pub fn downcast_for_message<T: 'static>(self) -> Option<BufferKey<T>>

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>

pub fn as_any_buffer_key(self) -> AnyBufferKey

Cast this into an AnyBufferKey

Trait Implementations

impl Accessor for JsonBufferKey

type Buffers = JsonBuffer

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 JsonBufferKey

type TargetBuffer = JsonBuffer

What kind of buffer this key can unlock.

fn create_key(buffer: &Self::TargetBuffer, 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 JsonBufferKey

fn clone(&self) -> JsonBufferKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonBufferKey

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

Formats the value using the given formatter.

impl<T: 'static + Send + Sync + Serialize + DeserializeOwned> From<BufferKey<T>> for JsonBufferKey

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

Converts to this type from the input type.

impl From<JsonBufferKey> for AnyBufferKey

fn from(value: JsonBufferKey) -> Self

Converts to this type from the input type.
