Trait NodeRestriction 

pub trait NodeRestriction: Send + Sync {
    // Required method
    fn r_is_ok(&self, router: &RouterStatusEntry) -> bool;
}

Interface for node restriction policies.

Implementations of this trait define criteria for filtering relay nodes. Multiple restrictions can be combined using NodeRestrictionList.

Implementing Custom Restrictions

Create custom restrictions by implementing this trait:

use vanguards_rs::node_selection::NodeRestriction;
use stem_rs::descriptor::router_status::RouterStatusEntry;

struct BandwidthRestriction {
    min_bandwidth: u64,
}

impl NodeRestriction for BandwidthRestriction {
    fn r_is_ok(&self, router: &RouterStatusEntry) -> bool {
        router.bandwidth.unwrap_or(0) >= self.min_bandwidth
    }
}

Thread Safety

Implementations must be Send + Sync to allow use across threads.

Required Methods

fn r_is_ok(&self, router: &RouterStatusEntry) -> bool

Returns true if the router passes this restriction.
