Module command 

Bounded command queue for off-main-thread mutations of ECS state.

• Capacity defaults to DEFAULT_QUEUE_CAPACITY (8192) and is configurable via CommandQueue::with_capacity.
• Overflow drops the command, logs, and emits a CommandQueueOverflow message.
• The TickStage::CommandDrain stage drains the queue on the main thread between Input and Systems.

Structs

CommandQueueOverflow

CommandReceiver

Consumer-side ECS resource, registered as a non-Send resource since the drain runs on the main thread.

CommandRegistry

Resource holding the per-TypeId handler table for Command::Typed.

Enums

Command

A deferred command applied during TickStage::CommandDrain.

Constants

Functions
