}

Collection of stuff used while creating the UnitGraph.

Fields

ws: &'a Workspace<'cfg>

config: &'cfg Config

unit_dependencies: UnitGraph

Stores the result of building the UnitGraph.

package_set: &'a PackageSet<'cfg>

usr_resolve: &'a Resolve

usr_features: &'a ResolvedFeatures

std_resolve: Option<&'a Resolve>

Like usr_resolve but for building standard library (-Zbuild-std).

std_features: Option<&'a ResolvedFeatures>

Like usr_features but for building standard library (-Zbuild-std).

is_std: bool

true while generating the dependencies for the standard library.

global_mode: CompileMode

The mode we are compiling in. Used for preventing from building lib thrice.

target_data: &'a RustcTargetData<'cfg>

profiles: &'a Profiles

interner: &'a UnitInterner

scrape_units: &'a [Unit]

dev_dependency_edges: HashSet<(Unit, Unit)>

A set of edges in unit_dependencies where (a, b) means that the dependency from a to b was added purely because it was a dev-dependency. This is used during connect_run_custom_build_deps.

Implementations

impl<'a, 'cfg> State<'a, 'cfg>

fn resolve(&self) -> &'a Resolve

Gets std_resolve during building std, otherwise usr_resolve.

fn features(&self) -> &'a ResolvedFeatures

Gets std_features during building std, otherwise usr_features.

fn activated_features( &self, pkg_id: PackageId, features_for: FeaturesFor ) -> Vec<InternedString>

fn is_dep_activated( &self, pkg_id: PackageId, features_for: FeaturesFor, dep_name: InternedString ) -> bool

fn get(&self, id: PackageId) -> &'a Package

fn deps( &self, unit: &Unit, unit_for: UnitFor ) -> Vec<(PackageId, Vec<&Dependency>)>

Returns a filtered set of dependencies for the given unit.

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.
