Trait SystemParam 

pub trait SystemParam: Sized {
    type Fetch: for<'w, 's> SystemParamFetch<'w, 's>;
}

Required Associated Types

type Fetch: for<'w, 's> SystemParamFetch<'w, 's>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
