Required Associated Types

type Item: SystemParam
where
    <Self::Item as SystemParam>::Fetch == Self

Required Methods

unsafe fn get_param(
    state: &'state mut Self,
    system_meta: &SystemMeta,
    world: &'world World,
    change_tick: u32
) -> Self::Item

Safety

This call might access any of the input parameters in an unsafe way. Make sure the data access is safe in the context of the system scheduler.
