Trait SystemParam

pub trait SystemParam: Sized {
    type Item<'world>: SystemParam;

    // Required method
    fn get_param<'world>(world: UnsafeWorldCell<'world>) -> Self::Item<'world>;
}

Required Associated Types

type Item<'world>: SystemParam

Required Methods

fn get_param<'world>(world: UnsafeWorldCell<'world>) -> Self::Item<'world>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
