Struct IndexModifiers 

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

IndexModifiers — the subset BaseAnchor can stack. Kept separate from Modifiers so anchor callers can’t accidentally write the top-level spatial form (which would be two surfaces for the same intent).

Fields

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.
