Struct Artifact 

pub struct Artifact { /* private fields */ }

Cached task artifact containing outputs and metadata.

Artifacts are immutable once created and contain:

• Metadata (task info, timestamps, cache key hash)
• Manifest (list of output files with hashes)
• Compressed output files

Implementations

impl Artifact

pub fn new( package_name: String, task_name: String, command: String, cache_key_hash: String, output_files: BTreeMap<PathBuf, Vec<u8>>, ) -> Result<Self>

Creates a new artifact from task outputs.

Arguments

• package_name - Name of the package
• task_name - Name of the task
• command - Command that was executed
• cache_key_hash - Hash of the cache key
• output_files - Map of relative paths to file contents

Errors

Returns an error if compression or serialization fails.

pub fn from_compressed(data: Vec<u8>) -> Result<Self>

Reads an artifact from compressed data.

Errors

Returns an error if decompression, deserialization, or verification fails.

pub fn metadata(&self) -> &ArtifactMetadata

Returns the artifact metadata.

pub fn manifest(&self) -> &ArtifactManifest

Returns the artifact manifest.

pub fn compressed_data(&self) -> &[u8]

Returns the compressed artifact data.

pub fn extract_outputs(&self, output_dir: &Path) -> Result<()>

Extracts output files from the artifact to the given directory.

Errors

Returns an error if extraction fails.

pub fn hash(&self) -> String

Computes the SHA-256 hash of the compressed artifact.
