Trait bevy::ecs::system::ReadOnlySystemParamFetch[−]

pub unsafe trait ReadOnlySystemParamFetch { }

Expand description

A SystemParamFetch that only reads a given World.

Safety

This must only be implemented for SystemParamFetch impls that exclusively read the World passed in to SystemParamFetch::get_param
