Struct CachedHubInfoEP 

pub struct CachedHubInfoEP {}

Provides the global client with cached details about the hubs.

Hub information is retrieved by default every minute, but this can be configured, see crate::servers::config::phc::ExtraConfig::hub_cache.

If a hub becomes unreachable, the last seen hub info will remain in the cache.

To see whether a hub is offline, you can compare the crate::api::hub::DynamicHubInfo::last_reload value of the crate::api::hub::InfoResp::dynamic field against the current time. If the difference is more than, say, three minutes, the hub is likely offline. (The hub currently updates every minute, PHC fetches these updates every minute, and pushes this after at most 5 seconds to the Apps.)

Trait Implementations

impl Debug for CachedHubInfoEP

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl EndpointDetails for CachedHubInfoEP

const METHOD: Method = http::Method::GET

const PATH: &'static str = ".ph/user/cached-hub-info"

type RequestType = NoPayload

type ResponseType = Result<CachedHubInfoResp, ErrorCode>

fn immutable_response() -> bool

Can the response be cached indefinitely?

fn add_to<App, F, Args: FromRequest + 'static>( app: &Rc<App>, sc: &mut ServiceConfig, handler: F, )

where AppMethod<App, F, Self>: Handler<Args>, <AppMethod<App, F, Self> as Handler<Args>>::Output: 'static + Responder,

Helper function to add this endpoint to a web::ServiceConfig.

fn caching_add_to<App, F>(app: &Rc<App>, sc: &mut ServiceConfig, handler: F)

where F: Fn(&App) -> Self::ResponseType, Self: Sized + 'static,

Like add_to, but runs handler only once, caching the result.
