 6## Inlay Hints
 7
 8The following configuration can be used to enable inlay hints for rust:
 9
10```json
11"inlayHints": {
12  "maxLength": null,
13  "lifetimeElisionHints": {
14  "useParameterNames": true,
15    "enable": "skip_trivial"
16  },
17  "closureReturnTypeHints": {
18    "enable": "always"
19  }
20}
21```
22
23to make the language server send back inlay hints when Zed has them enabled in the settings.
24
25Use
26
27```json
28"lsp": {
29  "$LANGUAGE_SERVER_NAME": {
30    "initialization_options": {
31      ....
32    }
33  }
34}
35```
36
37to override these settings.

39See https://rust-analyzer.github.io/manual.html#inlay-hints for more information.

41## Target directory
42
43The `rust-analyzer` target directory can be set in `initialization_options`:
44
45```json
46{
47  "lsp": {
48    "rust-analyzer": {
49      "initialization_options": {
50        "rust": {
51          "analyzerTargetDir": true
52        }
53      }
54    }
55  }
56}
57```
58
59A `true` setting will set the target directory to `target/rust-analyzer`. You can set a custom directory with a string like `"target/analyzer"` instead of `true`.
