Expand description

State for currently pending index file downloads.

Fields§

§pending: HashMap<usize, (Download<'gctx>, EasyHandle)>

When a download is started, it is added to this map. The key is a “token” (see Download::token). It is removed once the download is finished.

§pending_paths: HashSet<PathBuf>

Set of paths currently being downloaded. This should stay in sync with the pending field.

§sleeping: SleepTracker<(Download<'gctx>, Easy)>

Downloads that have failed and are waiting to retry again later.

§results: HashMap<PathBuf, CargoResult<CompletedDownload>>

The final result of each download.

§next: usize

The next ID to use for creating a token (see Download::token).

§progress: RefCell<Option<Progress<'gctx>>>

Progress bar.

§downloads_finished: usize

Number of downloads that have successfully finished.

§blocking_calls: usize

Number of times the caller has requested blocking. This is used for an estimate of progress.
