Struct cargo::core::package::PackageSet

pub struct PackageSet<'cfg> { /* fields omitted */ }

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.

Implementations

impl<'cfg> PackageSet<'cfg>

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

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

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 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.

pub fn lookup_mut(&mut self, id: PackageId) -> Option<&mut Package>

Get mutable access to an already downloaded package, if it’s already downoaded and it’s part of this set. Does not actually attempt to download anything if it’s not already downloaded.
