Struct ShardSet 

pub struct ShardSet {
    pub pack_hash: Hash,
    pub config: Config,
    pub shard_hashes: Vec<Hash>,
    pub commitment: Hash,
}

Manifest describing a set of shards encoding one pack.

In the wire protocol this is published alongside the shards under /packs/<pack_hash>/shards.manifest (see SPEC-PACK-SHARDS §2). A consumer fetches the manifest first, then fetches up to config.total_shards() shards in parallel, rejecting any whose BLAKE3 hash does not match.

Fields

pack_hash: Hash

BLAKE3 of the original pack bytes. Verified after reconstruction as the final defence against shard-set forgery.

config: Config

Reed-Solomon (minimum_shards, extra_shards) configuration used to produce this shard set. The decoder MUST use the same configuration.

shard_hashes: Vec<Hash>

BLAKE3 of each shard’s bytes, indexed by shard index. shard_hashes.len() MUST equal config.total_shards().

commitment: Hash

Commonware BMT root committing to all shards. Required by the commonware decoder for per-shard Merkle-proof checks. Stored here so the manifest is self-contained — a receiver does not need a second round-trip to fetch the commitment.

Trait Implementations

impl Clone for ShardSet

fn clone(&self) -> ShardSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShardSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ShardSet

impl PartialEq for ShardSet

fn eq(&self, other: &ShardSet) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
