Expand description

Helper for downloading crates.

Fields§

§set: &'a PackageSet<'gctx>§progress: RefCell<Progress<'gctx>>

Progress bar.

§first: Cell<bool>

Flag for keeping track of whether we’ve printed the Downloading message.

§largest: Cell<Option<(u64, InternedString)>>

Size (in bytes) and package name of the largest downloaded package.

§downloads_finished: Cell<u64>

Number of downloads that have successfully finished.

§downloaded_bytes: Cell<u64>

Total bytes for all successfully downloaded packages.

§pending: Cell<u64>

Number of currently pending downloads.

§start: Instant

Time when downloading started.

§_lock: CacheLock<'gctx>

Global filesystem lock to ensure only one Cargo is downloading one at a time.
