Crate ra_ap_project_model

In rust-analyzer, we maintain a strict separation between pure abstract semantic project model and a concrete model of a particular build system.

Pure model is represented by the [base_db::CrateGraph] from another crate.

In this crate, we are concerned with “real world” project models.

Specifically, here we have a representation for a Cargo project (CargoWorkspace) and for manually specified layout (ProjectJson).

Roughly, the things we do here are:

• Project discovery (where’s the relevant Cargo.toml for the current dir).
• Custom build steps (build.rs code generation and compilation of procedural macros).
• Lowering of concrete model to a [base_db::CrateGraph]

PackageRoot

PackageRoot describes a package root folder. Which may be an external dependency, or a member of the current workspace.
