pub trait Resource: Send + 'static { }Expand description
Marker trait for types that can be stored in a World.
Requires Send + 'static. Use #[derive(Resource)] to implement,
or new_resource! for newtype wrappers.
use nexus_rt::Resource;
#[derive(Resource)]
struct OrderBook {
bids: Vec<(f64, f64)>,
asks: Vec<(f64, f64)>,
}§Why not just Send + 'static?
Without the marker trait, two modules can independently register
u64 and silently collide. The Resource bound forces a newtype,
making collisions a compile error.
