Struct cargo::core::package::Downloads [−][src]
Helper for downloading crates.
Implementations
impl<'a, 'cfg> Downloads<'a, 'cfg>[src]
pub fn start(&mut self, id: PackageId) -> CargoResult<Option<&'a Package>>[src]
Starts to download the package for the id specified.
Returns None if the package is queued up for download and will
eventually be returned from wait_for_download. Returns Some(pkg) if
the package is ready and doesn’t need to be downloaded.
pub fn remaining(&self) -> usize[src]
Returns the number of crates that are still downloading.
pub fn wait(&mut self) -> CargoResult<&'a Package>[src]
Blocks the current thread waiting for a package to finish downloading.
This method will wait for a previously enqueued package to finish downloading and return a reference to it after it’s done downloading.
Panics
This function will panic if there are no remaining downloads.
