Struct FileTerm 

pub struct FileTerm {
    pub byte_range: FileRange,
    pub xorb_chunk_range: ChunkRange,
    pub xorb_block_start_index: usize,
    pub offset_into_first_range: u64,
    pub xorb_block: Arc<XorbBlock>,
    pub url_info: Arc<TermBlockRetrievalURLs>,
}

A single term in a file reconstruction, representing a contiguous byte range in the output file that maps to a chunk range within a xorb block.

Fields

byte_range: FileRange

xorb_chunk_range: ChunkRange

xorb_block_start_index: usize

offset_into_first_range: u64

xorb_block: Arc<XorbBlock>

url_info: Arc<TermBlockRetrievalURLs>

Implementations

impl FileTerm

pub fn extract_bytes(&self, xorb_block_data: &XorbBlockData) -> Bytes

pub async fn get_data_task( &self, client: Arc<dyn Client>, progress_updater: Option<Arc<ItemProgressUpdater>>, chunk_cache: Option<Arc<dyn ChunkCache>>, ) -> Result<Pin<Box<dyn Future<Output = Result<Bytes>> + Send + 'static>>>

Get a future that will retrieve and extract the data bytes for this file term.

If the xorb data is already cached, returns a future that immediately resolves (no progress report, since the block was already reported by the term that triggered the download). Otherwise, spawns a task that calls retrieve_data, which uses single-flight to ensure only one download per xorb block (other callers wait without acquiring CAS permits).

Trait Implementations

impl Clone for FileTerm

fn clone(&self) -> FileTerm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
