Trait bevy_ecs::system::ReadOnlySystemParam
source · pub unsafe trait ReadOnlySystemParam: SystemParam { }
Expand description
A SystemParam
that only reads a given World
.
§Safety
This must only be implemented for SystemParam
impls that exclusively read the World passed in to SystemParam::get_param
Object Safety§
This trait is not object safe.
