Struct AutocompleteState 

pub struct AutocompleteState {
    pub kind: TriggerKind,
    pub query: String,
    pub replace_range: Range<usize>,
    pub items: Vec<Suggestion>,
    pub highlighted: usize,
    pub scroll_offset: usize,
    pub max_visible_rows: usize,
    pub anchor: (u16, u16),
    pub opener: Option<char>,
}

State machine for the autocomplete popup.

Owned by the host (editor or search box) via the controller. The trigger context lives in kind + query + anchor; the visible window is scroll_offset..(scroll_offset+max_visible_rows). All scroll math is encapsulated here so the widget and the host stay dumb.

Fields

kind: TriggerKind

query: String

replace_range: Range<usize>

Byte range in the host buffer that will be overwritten on accept (the text between the trigger sigil and the cursor). The controller refreshes this every keystroke so the latest accept replaces the up-to-date prefix.

items: Vec<Suggestion>

highlighted: usize

scroll_offset: usize

max_visible_rows: usize

anchor: (u16, u16)

Screen anchor where the popup is rendered (column, row in cells). Host computes from the trigger byte offset.

opener: Option<char>

For a LinkFilter popup, the operator char that opened it (<, >, or =) so the title renders the matching sigil. None for Wikilink/Hashtag (fixed sigils) and until set from the trigger.

Implementations

impl AutocompleteState

pub fn new(kind: TriggerKind, anchor: (u16, u16)) -> Self

pub fn set_items(&mut self, items: Vec<Suggestion>)

Replaces the suggestion list, snaps highlight to the first row, and resets the scroll window. Called every time core returns a new query result.

pub fn is_empty(&self) -> bool

pub fn selected(&self) -> Option<&Suggestion>

The currently highlighted suggestion, or None when the list is empty.

pub fn visible_window(&self) -> (usize, usize)

Inclusive-exclusive range of item indices currently visible in the popup. Always ≤ max_visible_rows items.

pub fn has_more_above(&self) -> bool

pub fn has_more_below(&self) -> bool

pub fn hidden_above(&self) -> usize

Count of items hidden above the visible window.

pub fn hidden_below(&self) -> usize

Count of items hidden below the visible window.

pub fn move_highlight_down(&mut self)

pub fn move_highlight_up(&mut self)

pub fn page_down(&mut self)

pub fn page_up(&mut self)

pub fn home(&mut self)

pub fn end(&mut self)

Trait Implementations

impl Clone for AutocompleteState

fn clone(&self) -> AutocompleteState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AutocompleteState

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

Formats the value using the given formatter.
