Required Methods

fn spawn_system<I, O, S, Marker>(&mut self, system: S) -> SysId

where I: Send + Sync + 'static, O: Send + Sync + 'static, S: IntoSystem<I, O, Marker> + Send + Sync + 'static,

Schedule a system to be spawned.

Systems are not initialized until they are first run.

Returns the system id that will eventually reference the spawned system. It can be used to invoke the system with spawned_syscall() or SpawnedSyscallCommandsExt::spawned_syscall().

fn spawn_system_from<I, O>(&mut self, system: CallbackSystem<I, O>) -> SysId

where I: Send + Sync + 'static, O: Send + Sync + 'static,

Schedule a system to be spawned.

Returns the system id that will eventually reference the spawned system. It can be used to invoke the system with spawned_syscall() or SpawnedSyscallCommandsExt::spawned_syscall().

fn insert_system<I, O, S, Marker>( &mut self, entity: Entity, system: S ) -> Result<(), ()>

where I: Send + Sync + 'static, O: Send + Sync + 'static, S: IntoSystem<I, O, Marker> + Send + Sync + 'static,

Schedule a system to be inserted into the specified entity.

This is useful for constructing self-referential systems, e.g. for systems that only run once then clean themselves up.

Returns an error if the entity does not exist.

fn spawned_syscall<I>(&mut self, sys_id: SysId, input: I)

where I: Send + Sync + 'static,

Schedule a spawned system call.

It is the responsibility of the caller to correctly match the system entity with the target system signature.

Logs a warning if the system entity doesn’t exist.

Syntax sugar for spawned_syscall().

Object Safety

This trait is not object safe.
