Struct Backend 

pub struct Backend<C> { /* private fields */ }

Transport-agnostic LSP request handler.

Backend exposes inherent async methods mirroring the LSP requests. Front-ends (the swls binary’s tower_lsp adapter, or a future wasm dispatcher) call these directly. It is generic over the Client used to send server-to-client messages.

Implementations

impl<C: Client> Backend<C>

pub fn new( sender: CommandSender, client: C, tokens: Vec<SemanticTokenType>, ) -> Self

impl<C: Client> Backend<C>

pub async fn initialize( &self, init: InitializeParams, ) -> Result<InitializeResult>

pub async fn initialized(&self, _params: InitializedParams)

pub async fn did_change_workspace_folders( &self, params: DidChangeWorkspaceFoldersParams, )

pub async fn semantic_tokens_full( &self, params: SemanticTokensParams, ) -> Result<Option<SemanticTokensResult>>

pub async fn shutdown(&self) -> Result<()>

pub async fn references( &self, params: ReferenceParams, ) -> Result<Option<Vec<Location>>>

pub async fn prepare_rename( &self, params: TextDocumentPositionParams, ) -> Result<Option<PrepareRenameResponse>>

pub async fn rename( &self, params: RenameParams, ) -> Result<Option<WorkspaceEdit>>

pub async fn hover(&self, params: HoverParams) -> Result<Option<Hover>>

pub async fn inlay_hint( &self, params: InlayHintParams, ) -> Result<Option<Vec<InlayHint>>>

pub async fn formatting( &self, params: DocumentFormattingParams, ) -> Result<Option<Vec<TextEdit>>>

pub async fn on_type_formatting( &self, params: DocumentOnTypeFormattingParams, ) -> Result<Option<Vec<TextEdit>>>

pub async fn did_open(&self, params: DidOpenTextDocumentParams)

pub async fn did_change(&self, params: DidChangeTextDocumentParams)

pub async fn did_save(&self, params: DidSaveTextDocumentParams)

pub async fn goto_definition( &self, params: GotoDefinitionParams, ) -> Result<Option<GotoDefinitionResponse>>

pub async fn goto_type_definition( &self, params: GotoTypeDefinitionParams, ) -> Result<Option<GotoTypeDefinitionResponse>>

pub async fn code_action( &self, params: CodeActionParams, ) -> Result<Option<CodeActionResponse>>

pub async fn execute_command( &self, params: ExecuteCommandParams, ) -> Result<Option<Value>>

Handle workspace/executeCommand.

Currently only swls.allowProperty: adds the given property IRI to the user’s allowed_properties, both at runtime (clearing the warning) and on disk (so the choice survives restarts), then refreshes diagnostics.

pub async fn completion( &self, params: CompletionParams, ) -> Result<Option<CompletionResponse>>

Trait Implementations

impl<C> Debug for Backend<C>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
