Struct BuildCache 

pub struct BuildCache { /* private fields */ }

Content-addressed build cache backed by Arrow.

Stores compiled artifacts keyed by the SHA-256 hash of the source body. Same body → same hash → same compiled output → cache hit.

Implementations

impl BuildCache

pub fn new() -> Self

Create an empty cache.

pub fn get(&mut self, body_hash: &str) -> Option<&CacheEntry>

Look up a cached artifact by body hash.

pub fn put(&mut self, entry: CacheEntry)

Store a compiled artifact in the cache.

pub fn len(&self) -> usize

Number of cached artifacts.

pub fn is_empty(&self) -> bool

Whether the cache is empty.

pub fn stats(&self) -> &CacheStats

Current cache statistics.

pub fn remove(&mut self, body_hash: &str) -> bool

Remove a cached artifact by body hash. Returns true if found.

pub fn reset_stats(&mut self)

pub fn to_record_batch(&self) -> Result<RecordBatch, ArrowError>

Serialize cache to an Arrow RecordBatch.

pub fn from_record_batch(batch: &RecordBatch) -> Result<Self, String>

Deserialize cache from an Arrow RecordBatch.

pub fn save_to_parquet(&self, path: &Path) -> Result<(), Box<dyn Error>>

Save cache to a Parquet file.

pub fn load_from_parquet(path: &Path) -> Result<Self, Box<dyn Error>>

Load cache from a Parquet file.
