pub struct Downloads<'a, 'cfg> { /* private fields */ }

Expand description

Helper for downloading crates.

Implementations

source

impl<'a, 'cfg> Downloads<'a, 'cfg>

source

pub fn start(&mut self, id: PackageId) -> CargoResult<Option<&'a Package>>

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.

source

pub fn remaining(&self) -> usize

Returns the number of crates that are still downloading.

source

pub fn wait(&mut self) -> CargoResult<&'a Package>

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.
