Struct WasmContextSource 

pub struct WasmContextSource { /* private fields */ }

An async context-scope producer over a plugin’s ContextClient. Cheap to clone (the client is an mpsc Sender clone); every clone talks to the same actor / Store.

Implementations

impl WasmContextSource

pub fn new(client: ContextClient) -> Self

Build the adapter over a client bridge. (No connect/spec round-trip like completion — a context provider has no id/doc metadata; it is a pure producer keyed by the plugin that owns it.)

pub fn plugin_id(&self) -> PluginId

The host-issued id of the plugin behind this source.

pub async fn context_scopes( &self, buffer_id: u64, path: Option<&Path>, line_count: u32, tree: Option<Arc<SyntaxSnapshot>>, ) -> Result<Vec<ContextScope>, String>

Produce the structural context scopes for a buffer — the async producer the host calls OFF the render path when a reparse lands.

Graceful (§8, no blanking): the outer host error (trap / plugin-gone) and the inner guest WIT err both collapse to the String the caller logs — on an Err the caller keeps the buffer’s prior cached scopes rather than clearing them, so a failed refresh never reads as the feature breaking. A scope that fails to cross fails the whole batch as a typed error, never a silent drop.

Trait Implementations

impl AsyncContextSource for WasmContextSource

fn source_id(&self) -> u64

Stable id of the producing plugin — the teardown key. Two producers with the same id are the same plugin (a reload replaces rather than duplicates), mirroring AsyncGutterDecorationSource::source_id.

fn produce( &self, buffer_id: u64, path: Option<PathBuf>, line_count: u32, syntax: Option<Arc<dyn Any + Send + Sync>>, ) -> ContextFuture<'_>

Produce this buffer’s context scopes off the render path.

impl Clone for WasmContextSource

fn clone(&self) -> WasmContextSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmContextSource

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

Formats the value using the given formatter.
