Struct cargo::core::package::PackageSet

pub struct PackageSet<'cfg> {
    packages: HashMap<PackageId, LazyCell<Package>>,
    sources: RefCell<SourceMap<'cfg>>,
    config: &'cfg Config,
    multi: Multi,
    downloading: Cell<bool>,
    multiplexing: bool,
}

A set of packages, with the intent to download.

This is primarily used to convert a set of PackageIds to Packages. It will download as needed, or used the cached download if available.

Fields

packages: HashMap<PackageId, LazyCell<Package>>

sources: RefCell<SourceMap<'cfg>>

config: &'cfg Config

multi: Multi

downloading: Cell<bool>

Used to prevent reusing the PackageSet to download twice.

multiplexing: bool

Whether or not to use curl HTTP/2 multiplexing.

Implementations

impl<'cfg> PackageSet<'cfg>

pub fn new( package_ids: &[PackageId], sources: SourceMap<'cfg>, config: &'cfg Config ) -> CargoResult<PackageSet<'cfg>>

pub fn package_ids(&self) -> impl Iterator<Item = PackageId> + '_

pub fn packages(&self) -> impl Iterator<Item = &Package>

pub fn enable_download<'a>(&'a self) -> CargoResult<Downloads<'a, 'cfg>>

pub fn get_one(&self, id: PackageId) -> CargoResult<&Package>

pub fn get_many( &self, ids: impl IntoIterator<Item = PackageId> ) -> CargoResult<Vec<&Package>>

pub fn download_accessible( &self, resolve: &Resolve, root_ids: &[PackageId], has_dev_units: HasDevUnits, requested_kinds: &[CompileKind], target_data: &RustcTargetData<'cfg>, force_all_targets: ForceAllTargets ) -> CargoResult<()>

Downloads any packages accessible from the give root ids.

pub(crate) fn warn_no_lib_packages_and_artifact_libs_overlapping_deps( &self, ws: &Workspace<'cfg>, resolve: &Resolve, root_ids: &[PackageId], has_dev_units: HasDevUnits, requested_kinds: &[CompileKind], target_data: &RustcTargetData<'_>, force_all_targets: ForceAllTargets ) -> CargoResult<()>

Check if there are any dependency packages that violate artifact constraints to instantly abort, or that do not have any libs which results in warnings.

fn filter_deps<'a>( pkg_id: PackageId, resolve: &'a Resolve, has_dev_units: HasDevUnits, requested_kinds: &'a [CompileKind], target_data: &'a RustcTargetData<'_>, force_all_targets: ForceAllTargets ) -> impl Iterator<Item = (PackageId, &'a HashSet<Dependency>)> + 'a

pub fn sources(&self) -> Ref<'_, SourceMap<'cfg>>

pub fn sources_mut(&self) -> RefMut<'_, SourceMap<'cfg>>

pub fn add_set(&mut self, set: PackageSet<'cfg>)

Merge the given set into self.

Layout

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.
