A deferred command applied during TickStage::CommandDrain.

Variants

AssetLoaded

Carries an asynchronously decoded asset payload.

Fields

callback_id: u64

Identifier supplied by the requester when the asset was requested.

payload: Box<dyn Any + Send>

Decoded payload (image bytes, etc.) typed by the consumer.

NetworkResponse

Carries an HTTP response payload.

Fields

callback_id: u64

Identifier supplied at request time.

status: u16

HTTP status code.

body: Vec<u8>

Response body bytes.

ScriptUpdate(Box<dyn Any + Send>)

Carries a script-produced state mutation.

SetProperty

Writes a typed value into the PropertyStore.

Drained in TickStage::CommandDrain via apply_property_commands. The per-App queue is the intended home for external property writes, but the global EXTERNAL_TX / EXTERNAL_RX ring in property_store is still what the C-ABI crate and the async tasks use; this variant has no producer yet.

Fields

key: PropertyKey

Target property key.

value: PropertyValue

New value to write.

Typed

Strongly-typed custom command, dispatched via CommandRegistry.

Replaces blind Custom(Box<dyn Any>) downcasts: the receiving plugin registers a handler for its concrete payload type with crate::app::App::register_command and the drain dispatches by TypeId.

Fields

type_id: TypeId

Concrete payload type id used to route the command to its registered handler.

payload: Box<dyn Any + Send>

Boxed payload.

Custom(Box<dyn Any + Send>)

Free-form variant retained for backward compatibility with callers that have not yet migrated to Self::Typed.
