Struct ChunkManifest 

pub struct ChunkManifest {
    pub chunk_id: String,
    pub chunk_index: usize,
    pub original_size: usize,
    pub fragment_locations: Vec<FragmentLocation>,
}

Manifest entry for a single chunk of a file.

Fields

chunk_id: String

BLAKE3 hash prefix (16 hex chars) of the encrypted chunk (i.e. the data that was fed into rlnc::encode).

Encryption is performed with crate::storage::ChunkCipher before RLNC coding, so Pouch nodes never hold plaintext data.

chunk_index: usize

Zero-based index of this chunk in the file.

original_size: usize

Original byte count of this chunk (before padding and encryption). Used to trim padding after decoding.

fragment_locations: Vec<FragmentLocation>

Where each of the n fragments lives in the network.

Implementations

impl ChunkManifest

pub fn fragments_on_peer<'a>( &'a self, peer_id: &str, ) -> Vec<&'a FragmentLocation>

Fragment locations on a specific peer (for fragment-fetch routing).

pub fn holder_peers(&self) -> Vec<&str>

All Pouch peer IDs that hold at least one fragment of this chunk.
