}

Trait for reading from a recorded run’s store.

This trait abstracts over reading from either an on-disk store directory (via RecordReader) or from an inner store.zip within a portable archive (via PortableStoreReader).

Required Methods

fn read_cargo_metadata(&mut self) -> Result<String, RecordReadError>

Returns the cargo metadata JSON from the store.

fn read_test_list(&mut self) -> Result<TestListSummary, RecordReadError>

Returns the test list summary from the store.

fn read_record_opts(&mut self) -> Result<RecordOpts, RecordReadError>

Returns the record options from the store.

fn read_rerun_info(&mut self) -> Result<Option<RerunInfo>, RecordReadError>

Returns the rerun info from the store, if this is a rerun.

Returns Ok(None) if this run is not a rerun (the file doesn’t exist).

fn load_dictionaries(&mut self) -> Result<(), RecordReadError>

Loads the dictionaries from the store.

This must be called before reading output files.

fn read_output(&mut self, file_name: &str) -> Result<Vec<u8>, RecordReadError>

Reads output for a specific file from the store.

The file_name should be the value from ZipStoreOutput::file_name, e.g., “test-abc123-1-stdout”.

Panics

Panics if load_dictionaries has not been called first.

fn extract_file_to_path( &mut self, store_path: &str, output_path: &Utf8Path, ) -> Result<u64, RecordReadError>

Extracts a file from the store to a path, streaming directly.

The store_path is relative to the store root (e.g., meta/test-list.json). Returns the number of bytes written.
