272== Non-Cargo Based Projects
273
274rust-analyzer does not require Cargo.
275However, if you use some other build system, you'll have to describe the structure of your project for rust-analyzer in the `rust-project.json` format:
276
277[source,TypeScript]
278----
279interface JsonProject {
280 /// The set of paths containing the crates for this project.
281 /// Any `Crate` must be nested inside some `root`.
282 roots: string[];
283 /// The set of crates comprising the current project.
284 /// Must include all transitive dependencies as well as sysroot crate (libstd, libcore and such).
285 crates: Crate[];
286}
287
288interface Crate {
289 /// Path to the root module of the crate.
290 root_module: string;
291 /// Edition of the crate.
292 edition: "2015" | "2018";
293 /// Dependencies
294 deps: Dep[];
295 /// The set of cfgs activated for a given crate, like `["unix", "feature=foo", "feature=bar"]`.
296 cfg: string[];
297
298 /// value of the OUT_DIR env variable.
299 out_dir?: string;
300 /// For proc-macro crates, path to compiles proc-macro (.so file).
301 proc_macro_dylib_path?: string;
302}
303
304interface Dep {
305 /// Index of a crate in the `crates` array.
306 crate: number,
307 /// Name as should appear in the (implicit) `extern crate name` declaration.
308 name: string,
309}
310----
311
312This format is provisional and subject to change.
313Specifically, the `roots` setup will be different eventually.
314
315There are tree ways to feed `rust-project.json` to rust-analyzer:
316
317* Place `rust-project.json` file at the root of the project, and rust-anlayzer will discover it.
318* Specify `"rust-analyzer.linkedProjects": [ "path/to/rust-project.json" ]` in the settings (and make sure that your LSP client sends settings as a part of initialize request).
319* Specify `"rust-analyzer.linkedProjects": [ { "roots": [...], "crates": [...] }]` inline.
320
321See https://github.com/rust-analyzer/rust-project.json-example for a small example.
