}

A trait for providing code completions based on the current input state and context.

Required Methods

fn completions( &self, text: &Rope, offset: usize, trigger: CompletionContext, window: &mut Window, cx: &mut Context<'_, InputState>, ) -> Task<Result<CompletionResponse>>

Fetches completions based on the given byte offset.

• The offset is in bytes of current cursor.

fn is_completion_trigger( &self, offset: usize, new_text: &str, cx: &mut Context<'_, InputState>, ) -> bool

Determines if the completion should be triggered based on the given byte offset.

This is called on the main thread.

Provided Methods

fn inline_completion( &self, _rope: &Rope, _offset: usize, _trigger: InlineCompletionContext, _window: &mut Window, _cx: &mut Context<'_, InputState>, ) -> Task<Result<InlineCompletionResponse>>

Fetches an inline completion suggestion for the given position.

This is called after a debounce period when the user stops typing. The provider can analyze the text and cursor position to determine what inline completion suggestion to show.

Arguments

• rope - The current text content
• offset - The cursor position in bytes

fn inline_completion_debounce(&self) -> Duration

Returns the debounce duration for inline completions.

Default: 300ms

fn resolve_completions( &self, _completion_indices: Vec<usize>, _completions: Rc<RefCell<Box<[Completion]>>>, _: &mut Context<'_, InputState>, ) -> Task<Result<bool>>
