Struct DiscussionReplyGraph 

pub struct DiscussionReplyGraph { /* private fields */ }

Adjacency graph built from a flat reply list.

Implementations

impl DiscussionReplyGraph

pub fn from_flat(replies: &[DiscussionReply]) -> Self

Build a reply graph from a flat list, preserving input order for siblings.

Replies whose parent is missing from the list become roots (orphan tolerance). Duplicate ids keep the last occurrence.

pub fn get(&self, id: &str) -> Option<&DiscussionReply>

Lookup a reply by id.

pub fn child_ids(&self, parent_id: &str) -> &[String]

Ordered child ids for a parent reply.

pub fn visible_replies( &self, focus: &DiscussionFocus, mode: DiscussionViewMode, sort: DiscussionSort, ) -> Vec<&DiscussionReply>

Project visible replies for the current focus, mode, and sort.

pub fn depth_in_view(&self, id: &str, focus: &DiscussionFocus) -> u32

Depth of id relative to the current focus anchor (anchor = 0).

pub fn is_descendant_of(&self, id: &str, ancestor_id: &str) -> bool

Whether id is ancestor_id or a descendant of ancestor_id.
