Struct Chunk

pub struct Chunk<H: Hasher> {
    pub shard: Vec<u8>,
    pub index: u16,
    pub proof: Proof<H>,
}

Data that has been encoded using a Reed-Solomon coder and inserted into a bmt.

Fields

shard: Vec<u8>

The shard of encoded data.

index: u16

The index of Chunk in the original data.

proof: Proof<H>

The proof of the shard in the bmt at the given index.

Implementations

impl<H: Hasher> Chunk<H>

pub fn new(shard: Vec<u8>, index: u16, proof: Proof<H>) -> Self

Create a new Chunk from the given shard, index, and proof.

pub fn verify(&self, root: &H::Digest) -> bool

Verify a Chunk against the given root.
