Struct ListGrouper 

pub struct ListGrouper { /* private fields */ }

Tracks active list entities across consecutive blocks so that items belonging to the same logical list share a single list entity.

Uses a vec indexed by indent level. When indent decreases, deeper entries are truncated so that outer lists resume correctly.

Implementations

impl ListGrouper

pub fn new() -> Self

pub fn try_reuse(&mut self, style: &ListStyle, indent: u32) -> Option<EntityId>

Returns an existing list entity id if the style and indent match a previously registered list at this level. Returns None if a new list entity must be created (caller should then call register).

pub fn try_reuse_delim( &mut self, style: &ListStyle, indent: u32, prefix: &str, suffix: &str, ) -> Option<EntityId>

Like try_reuse but also requires the ordered-list delimiter affixes to match. Used by the djot importer, which preserves the ./)/( ) delimiter on the List entity.

pub fn register(&mut self, id: EntityId, style: ListStyle, indent: u32)

Register a newly created list entity at the given indent level.

pub fn register_delim( &mut self, id: EntityId, style: ListStyle, indent: u32, prefix: String, suffix: String, )

Like register but records the ordered-list delimiter affixes so subsequent try_reuse_delim calls can distinguish lists with different delimiters.

pub fn reset(&mut self)

Clear all tracking. Call on non-list blocks, tables, or frame boundaries.

impl Default for ListGrouper

fn default() -> ListGrouper
