Expand description

Helper for downloading crates.

Fields§

§pending: HashMap<usize, (Download<'cfg>, 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 pending.

§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<'cfg>>>

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.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
