Trait bevy_internal::ecs::system::SystemBuffer

Expand description

Types that can be used with Deferred<T> in systems. This allows storing system-local data which is used to defer World mutations.

Types that implement SystemBuffer should take care to perform as many computations up-front as possible. Buffers cannot be applied in parallel, so you should try to minimize the time spent in SystemBuffer::apply.

Required Methods§

source

fn apply(&mut self, system_meta: &SystemMeta, world: &mut World)

Applies any deferred mutations to the World.
