Struct EarleyParseOptions 

pub struct EarleyParseOptions {
    pub propagate_positions: bool,
    pub ambiguity: Ambiguity,
}

Per-parse Earley options. Mirrors crate::ParseOptions (LALR) plus the ambiguity field the Earley engine alone honors (Lark’s ambiguity=). Earley owns its own options type — LALR’s has no ambiguity and lives behind the engine boundary.

Fields

propagate_positions: bool

Compute per-node crate::model::Meta, delegated through the chain’s shared position core.

ambiguity: Ambiguity

Resolve (pick one derivation by summed priority) | Explicit (wrap derivations in _ambig/_iambig/_inter). Forest is deferred from v1.
