Trait bevy::ecs::system::ReadOnlySystemParam

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.
