Struct Context 

pub struct Context { /* private fields */ }

Per-request handle to framework state (see ADR 0009).

The handle exposes connection-scoped capabilities — the established Workspace (initialization metadata, roots, workspace folders, and the read-only DocumentsView) and the Client — without exposing protocol-owned queues or registries.

Implementations

impl Context

pub fn request_id(&self) -> Option<&RequestId>

The JSON-RPC request ID, or None while handling a notification.

pub fn span(&self) -> &Span

The tracing span associated with the incoming call.

pub fn documents(&self) -> DocumentsView

The connection’s documents, as a read-only DocumentsView — the same view Workspace::documents hands out.

The framework owns and mutates the documents; a handler reads the retained documents and converts positions through this view, and a registered document hook sees it already carrying the built-in mutation (ADR 0018).

pub fn client(&self) -> Client

A cheap clone of the typed handle for this connection’s LSP client.

pub fn workspace(&self) -> &Workspace

The connection’s Workspace, established from InitializeParams during the initialize transaction (ADR 0017, ADR 0018): the one cheap, shared, read-only view of the initialization metadata, roots, workspace folders, and documents every handler observes.

pub fn publish_diagnostics( &self, params: PublishDiagnosticsParams, ) -> Result<(), ClientError>

Push a textDocument/publishDiagnostics notification through the connection’s typed Client (fire-and-forget); see Client::publish_diagnostics for the exact semantics.

Serialization and enqueue failures are returned to the caller (the client helper also reports them through tracing). A failed publish never invalidates the handler that triggered it, so a handler that treats publishing as best effort may simply drop the error.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.
