To use this extension:

  1. Right click a file in the file editor.
  2. Select Open in OSS Code Search.

  2. Type settings in the search field.
  3. Click Preferences: Open Settings (JSON).

Language specific extensions

FIDL language support

FIDL Language Support provides syntax support and LSP-based language features in FIDL.

Rust-analyzer is a Language Server Protocol (LSP) implementation for the Rust language.

To use rust-analyzer with VS Code, Fuchsia recommends:

Configure workflow

Using the fuchsia.code-workspace configuration file will set recommended defaults for using rust-analyzer on Fuchsia.

Beyond those defaults, here are some optional settings you may want to add to your settings.json:

  // optional: only show summary docs for functions (keeps tooltips small)
  "rust-analyzer.signatureInfo.detail": "parameters",
  // optional: don't activate parameterHints automatically
  "editor.parameterHints.enabled": false,

Fuchsia SDK extensions


The Fuchsia SDK uses the Bazel build system. The Bazel extension can build and run components directly from VS Code.
