Struct Hub 

pub struct Hub { /* private fields */ }

The host’s jobs and the page’s event stream.

Implementations

impl Hub

pub fn new(root: &Path) -> Arc<Self>

A hub for the project at root.

pub fn subscribe(&self) -> Receiver<String>

Every event from now on, as JSON text.

pub fn job(&self) -> Option<JobView>

The job, if one ran since the host started.

pub fn waiting(&self) -> Option<Value>

What waits for the person now (an ask or question event).

pub fn answer(&self, id: u64, reply: Reply) -> Result<(), String>

Answers what waits; Err when nothing does, or something else does.

pub fn stop(&self)

Asks the running job to stop before its next task; a call waiting for the person is answered with “stop” (it keeps waiting, resumably).

pub fn exclusive<T>(&self, f: impl FnOnce() -> T) -> Result<T, String>

Runs f while no job runs and none can start — for a short change to the checkout (a commit): the check and the change are one step.

Errors

A job is working.

pub fn start( self: &Arc<Self>, run: Runnable, input: Option<String>, feature: Option<String>, command: String, ) -> Result<u64, String>

Starts run (with input for actions that take one) for feature; Err when a job is already working.
