Struct Observers 

pub struct Observers { /* private fields */ }

Handle that can be used to inform the server when changes are detected.

Implementations

impl Observers

pub fn relative_path(&self) -> String

pub async fn stay_active(&self)

pub async fn notify_change(&self)

Inform the server that a change to the underlying resource has potentially occurred. The server responds by re-executing synthetic Get or Fetch requests roughly matching the original client request, then delivering the results to the peer. Note that spurious changes will be delivered if this method is spammed so callers must take care to ensure it is only invoked when a genuine change is expected.

Note that a sequence number will be generated for you if one is omitted from response in the re-executed request. If you wish to provide your own, simply set the observe value in the response with response.message.set_observe_value(...). Be sure that if you do this, you are taking care that the sequence number does not run backwards within 256 seconds as per: RFC 7641, section 4.4
