Struct CompletionService 

pub struct CompletionService { /* private fields */ }

The completion service.

Implementations

impl CompletionService

pub fn new() -> Self

Create a new service with the built-in providers pre-registered.

pub fn register(&mut self, provider: Box<dyn CompletionProvider>)

Register a completion provider.

pub fn unregister(&mut self, id: &CompletionSourceId)

Unregister a provider by id.

pub fn request( &mut self, ctx: &CompletionContext, buffer_window: &[u8], ) -> Vec<CompletionCandidate>

Request completion from all enabled providers.

buffer_window is the pre-sliced byte range corresponding to ctx.scan_range. The caller (Editor) is responsible for extracting this from the buffer, which keeps the service decoupled from the buffer internals.

Returns the synchronously-available candidates, already merged and sorted. Any providers that return Pending are tracked internally; their results should be supplied later via supply_async_results.

pub fn supply_async_results( &mut self, request_id: u64, candidates: Vec<CompletionCandidate>, ) -> Option<Vec<CompletionCandidate>>

Supply results from an async provider (e.g., LSP).

Returns the merged, re-ranked candidate list including both the new async results and any previously supplied candidates.

pub fn has_pending(&self) -> bool

Check if there are pending async provider requests.

pub fn providers(&self) -> &[Box<dyn CompletionProvider>]

Access the registered providers (read-only).
