Struct BuildCache 

pub struct BuildCache {
    pub config_hash: String,
    pub entries: BTreeMap<PathBuf, CacheEntry>,
}

Incremental build cache. Maps relative path → CacheEntry.

config_hash auto-invalidates entries whenever either the project config or the nodex binary version changes — the latter guards against struct-shape drift in Node / Edge / RawEdge after an upgrade. The hash is computed by builder::build; this struct only stores it for comparison on the next load.

Fields

config_hash: String

entries: BTreeMap<PathBuf, CacheEntry>

Implementations

impl BuildCache

pub fn load( cache_path: &Path, current_config_hash: &str, ) -> (Self, Option<String>)

Load cache from disk. Returns empty cache when the file is absent, unreadable, corrupt, or was produced under a different config hash. The second return value is an optional warning string explaining why — callers surface it so users see why an unexpectedly-slow rebuild is happening.

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

Save cache to disk.

pub fn get(&self, rel_path: &Path, content: &str) -> Option<&CacheEntry>

Get cached parse result if fresh.

pub fn insert( &mut self, rel_path: PathBuf, content: &str, node: Node, raw_edges: &[RawEdge], )

Store a parse result.

pub fn retain_paths(&mut self, valid_paths: &[PathBuf])

Remove entries for paths no longer in scope.
