Struct DownloadTarget 

pub struct DownloadTarget<'a> {
    pub hash: [u8; 32],
    pub total_bytes: u64,
    pub dest: &'a Path,
    pub ranges: Option<&'a [(u64, u64)]>,
}

One blob to fetch and where to write it: the content hash (the bao root), its total_bytes (authoritative for keying the store and sizing the fetch), the caller-chosen dest path the .partial and final file are keyed by, and the byte ranges to fill.

Fields

hash: [u8; 32]

The blob’s BLAKE3 content address (its bao root); every ingested byte is verified against it.

total_bytes: u64

The blob’s content length in bytes.

dest: &'a Path

Where to write the finished blob. The .partial store and the promoted final file are keyed by this path, so the finished file IS dest.

ranges: Option<&'a [(u64, u64)]>

The (offset, len) byte ranges to fill, or None for the whole blob. The fetch promotes the blob only when every byte is present, so a caller that writes the bytes outside them itself (a bundle entry’s donor splice) finds them in the .partial beside dest.
