Struct LspManager 

pub struct LspManager { /* private fields */ }

Manages LSP servers lazily — one per language.

When a file is changed, the manager detects the language, spawns a server if needed, notifies it, then pulls diagnostics. Servers that fail to start are marked broken and not retried for the session.

Implementations

impl LspManager

pub fn new(workspace_root: PathBuf) -> Self

Create a new LSP manager rooted at workspace_root.

pub async fn notify_file_changed(&self, path: &Path) -> Vec<Diagnostic>

Notify that a file was changed (written/edited/patched).

Reads the file content, spawns the language server lazily, sends didOpen/didChange, waits a debounce period, then pulls diagnostics.

Returns empty if the language is unsupported, the server is broken, or the file cannot be read.

pub async fn diagnostics(&self, path: &Path) -> Vec<Diagnostic>

Get diagnostics for a file on demand (without notifying a change).
