Struct OrderBookBlob 

Source 
pub struct OrderBookBlob {
    pub id: BlobId,
    pub exists: bool,
    pub blob: Blob,
    pub data_blobs: Vec<Blob>,
}
Expand description

Result of building the blob payload for an OrderBook contract.

The proxy fallback (run_external_blob) can only target a single blob, so for any contract bytecode that doesn’t fit in one blob-upload transaction we split it into multiple data_blobs and generate a tiny loader blob that, when LDC’d by the proxy, loads every data blob in order and then jumps into the reconstituted code. id / blob are that loader blob — the value the proxy will target as INITIAL_TARGET. data_blobs are the chunked code blobs the loader references; they must be uploaded before (or in the same set of transactions as) the loader blob.

Fields§

§id: BlobId

BlobId of the loader blob — this is what the proxy points at.

§exists: bool

Whether the loader blob is already on chain (cheap dedup).

§blob: Blob

The loader blob: a small piece of bytecode that, when executed by the proxy, LDCs data_blobs in order and jumps into them.

§data_blobs: Vec<Blob>

The chunked code blobs the loader references. Empty for tiny contracts that fit in a single blob (in that case blob IS the chunk and the loader stub round-trips trivially).
