Struct BacklinkIndex 

pub struct BacklinkIndex { /* private fields */ }

Bidirectional link index.

Maintains forward links (source → targets) and backward links (target → sources) for O(1) lookup.

Implementations

impl BacklinkIndex

pub fn new() -> Self

Create a new empty index.

pub fn index_file(&mut self, path: &str, content: &str)

Index all links in a file’s content.

Replaces any previously indexed links for this file (incremental update). Markdown links only — wikilinks are not resolved.

pub fn index_file_with( &mut self, path: &str, content: &str, stem_index: &StemIndex, )

Index both markdown links AND wikilinks. Wikilink targets are resolved against stem_index (basename → paths) so a bare [[Rust]] lands under the canonical path it actually points at. Ambiguous/unresolved wikilinks are silently skipped — they’re not indexed, so a later rename of any single candidate won’t rewrite them (design doc §6).

pub fn remove_file(&mut self, path: &str)

Remove a file from the index.

pub fn backlinks_for(&self, path: &str) -> Vec<Backlink>

Get all backlinks pointing to a file (files that reference this one).

pub fn sources_for(&self, target: &str) -> HashSet<String>

Get the set of source files that link to target (the backward index entry). Used by note_move to find every file whose links must be rewritten when the target is renamed.

pub fn forward_links_for(&self, path: &str) -> Vec<String>

Get all forward links from a file (files this one references).

pub fn backlink_count(&self, path: &str) -> usize

Get the number of backlinks for a file.

pub fn link_graph(&self) -> LinkGraph

Get the full link graph for visualization.

pub fn connection_strength(&self, path_a: &str, path_b: &str) -> usize

Compute connection strength between two files (shared backlink sources).

pub fn len(&self) -> usize

Number of files in the index.

pub fn is_empty(&self) -> bool

Whether the index is empty.

pub fn clear(&mut self)

Clear all indexed data.
