Struct Modifiers 

pub struct Modifiers {
    pub near: Option<Box<Selector>>,
    pub below: Option<Box<Selector>>,
    pub above: Option<Box<Selector>>,
    pub left_of: Option<Box<Selector>>,
    pub right_of: Option<Box<Selector>>,
    pub inside: Option<Box<Selector>>,

    pub nth: Option<usize>,
    pub first: Option<bool>,
    pub last: Option<bool>,
}

Modifier set stackable on Text / Id / Label / Role base forms. Spatial keys (near/below/above/leftOf/rightOf/inside) carry recursive selectors that resolve to an anchor node; index keys (nth/first/last) pick from the surviving candidate list.

Fields

near: Option<Box<Selector>>

Anchor sub-selector — candidate must be geometrically near it.

below: Option<Box<Selector>>

Anchor sub-selector — candidate must be below it (larger y center).

above: Option<Box<Selector>>

Anchor sub-selector — candidate must be above it (smaller y center).

left_of: Option<Box<Selector>>

Anchor sub-selector — candidate must be to its left.

right_of: Option<Box<Selector>>

Anchor sub-selector — candidate must be to its right.

inside: Option<Box<Selector>>

Anchor sub-selector — candidate must be geometrically inside it.

ancestor: Option<Box<Selector>>

Ancestor sub-selector — candidate’s a11y tree parent chain (recursive ancestors, excluding self) must contain at least one node matching this sub-selector. Different from Modifiers::inside (geometric bounds-containment): ancestor walks the a11y tree parent chain — structural filter, not spatial. Use this to disambiguate same-label candidates living under different ancestor subtrees (e.g. a bottom tab and a sub-tab both labeled "Tracking").

nth: Option<usize>

Pick the nth match (0-indexed) from the surviving candidates.

first: Option<bool>

Pick the first match (true) — overridden by nth if both set.

last: Option<bool>

Pick the last match (true) — overridden by nth if both set.
