Struct DepGraph 

pub struct DepGraph { /* private fields */ }

Dependency graph mapping pages to their dependencies.

Implementations

impl DepGraph

pub fn new() -> Self

Creates an empty dependency graph.

pub fn load(site_dir: &Path) -> Self

Loads from .ssg-deps.json in the site directory. Returns an empty graph if the file is missing or corrupt.

pub fn save(&self, site_dir: &Path) -> Result<()>

Persists the graph to .ssg-deps.json.

pub fn add_dep(&mut self, page: &Path, dep: &Path)

Records that page depends on dep.

pub fn deps_for(&self, page: &Path) -> Option<&HashSet<PathBuf>>

Returns the dependencies for a given page.

pub fn invalidated_pages(&self, changed: &[PathBuf]) -> Vec<PathBuf>

Given a list of changed files, returns all pages that need rebuilding — either because they changed directly, or because one of their dependencies changed.

pub fn page_count(&self) -> usize

Returns the total number of tracked pages.

pub fn clear(&mut self)

Clears all dependency entries.
