Struct Activity 

pub struct Activity(/* private fields */);

What the relay is doing for each of a workspace’s tabs, read from anywhere and cheaply.

The screen has to be able to tell a tab that is waiting on a model from one that has been quiet for a while, and the relay is the only side of a request that knows: the container’s script hands it over and gets the answer back, so nothing between the harness and the provider is left holding a moment in time. A clone is a second pointer at the same counts, so a screen and the relay share one truth rather than two copies that can drift apart.

Implementations

impl Activity

pub fn busy(&self, token: &str) -> bool

Whether a request of token is on its way to a provider right now.

A lock that cannot be taken says it is not. A screen reading this is answering a person who is waiting, and waiting on a count that a poisoned lock would hold forever helps nobody.

pub fn last_finished(&self, token: &str) -> Option<Instant>

When the last request of token finished, or None when it has not finished one: a token no tab has, and a token whose every request was refused before it reached a route, both have no time.
