Struct ParseOptions 

pub struct ParseOptions {
    pub propagate_positions: bool,
}

Per-parse options.

Fields

propagate_positions: bool

Compute per-node crate::model::Meta with Lark’s container fallback. On: every Tree gets a crate::model::Meta in ParsedTree::meta_arena (Empty or Positioned), computed reduce-time from the raw children so filter_out edge tokens still bound a node’s span (see lalr::materialize). Off: zero-cost — no scan runs, meta_arena stays empty, every Tree.meta = MetaIdx::NONE.
