Crate ra_ap_project_model
source · [−]Expand description
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 conserned 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
Structs
CargoWorkspace
represents the logical structure of, well, a Cargo
workspace. It pretty closely mirrors cargo metadata
output.
More or less AbsPathBuf
with non-None parent.
Information associated with a cargo crate
PackageRoot
describes a package root folder.
Which may be an external dependency, or a member of
the current workspace.
Roots and crates that compose this Rust project.
Information associated with a package’s target
Enums
A set of cfg-overrides per crate.
Describes how to set the rustc source directory.
Crates to disable #[cfg(test)]
