Struct Affinity

pub struct Affinity { /* private fields */ }

Policy that selects targets based on past successes–if a target was used successfully in a past execution, it will be recommended first.

Trait Implementations

impl Default for Affinity

fn default() -> Affinity

Returns the “default value” for a type.

impl Policy for Affinity

type CacheItem = Uri

Type of item stored in a client’s cache.

type Ordering = AffinityUriIter

Iterator of indices used to order cache items.

fn refresh_cache<'life0, 'life1, 'async_trait, Resolver>( &'life0 self, client: &'life1 SrvClient<Resolver, Self>, ) -> Pin<Box<dyn Future<Output = Result<Cache<Self::CacheItem>, Error<Resolver::Error>>> + Send + 'async_trait>>

where Resolver: 'async_trait + SrvResolver, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Obtains a refreshed cache for a client.

fn order(&self, uris: &[Uri]) -> Self::Ordering

Creates an iterator of indices corresponding to cache items in the order a SrvClient should try using them to perform an operation.

fn cache_item_to_uri(item: &Self::CacheItem) -> &Uri

Converts a reference to a cached item into a reference to a Uri.

fn note_success(&self, uri: &Uri)

Makes any policy adjustments following a successful execution on uri.

fn note_failure(&self, uri: &Uri)

Makes any policy adjustments following a failed execution on uri.
