Struct DataFrame 

pub struct DataFrame {
    pub kind: u64,
    pub hash: Option<u64>,
    pub index: Option<u64>,
    pub total: Option<u64>,
    pub data: Buffer,
    pub next: Option<Vec<Cid>>,
}

Representation of a Kind::DataFrame node from the firehose.

Fields

kind: u64

Kind discriminator copied from the CBOR payload.

hash: Option<u64>

Optional rolling hash for the data chunk.

index: Option<u64>

Optional chunk index within the full payload.

total: Option<u64>

Optional total number of chunks.

data: Buffer

Raw bytes contained in this chunk.

next: Option<Vec<Cid>>

Optional list of CIDs pointing to continuation chunks.

Implementations

impl DataFrame

pub fn from_bytes(data: Vec<u8>) -> Result<DataFrame, SharedError>
