Expand description

Collection of stuff used while creating the `UnitGraph`.

## Fields§

§`ws: &'a Workspace<'gctx>`§`gctx: &'gctx GlobalContext`§`unit_dependencies: UnitGraph`

Stores the result of building the `UnitGraph`.

§`package_set: &'a PackageSet<'gctx>`§`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.

§`intent: UserIntent`

The high-level operation requested by the user. Used for preventing from building lib thrice.

§`target_data: &'a RustcTargetData<'gctx>`§`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§

## 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.
