Trait for YAML parsers that convert token streams to events

Functions

close_open_collections 🔒

has_open_document 🔒

Walks back through events looking for an unclosed DocumentStart (i.e. one without a matching DocumentEnd after it). Returns true if the parser is still inside a document.

has_unclosed_flow_collection 🔒

Emit MappingEnd / SequenceEnd events to close any unbalanced collection starts in events. Called before emitting a DocumentEnd when an outer construct (e.g. a new --- marker) forces the previous document closed without going through the usual indent-driven BlockEnd token path. Also synthesises implicit empty scalars for mappings that have an odd child-event count (i.e. a key without a value before the close). Return true when there is at least one flow collection still open (a SequenceStart / MappingStart with flow_style=true without a matching …End afterwards). Used at end-of-stream to enforce §7.4.

innermost_mapping_has_odd_children 🔒

Return true when the innermost still-open mapping has an odd number of children — i.e. a key has been emitted but its value has not. Used to decide when to synthesise an implicit empty scalar.

second_root_node_present 🔒

Walk events to detect a document that already contains a closed root-level node. Returns true when the second root node arrives and the existing event stack has no unmatched MapStart/SeqStart.
