Struct tendermint::block::Id

pub struct Id {
    pub hash: Hash,
    pub part_set_header: PartSetHeader,
}

Block identifiers which contain two distinct Merkle roots of the block, as well as the number of parts in the block.

https://github.com/tendermint/spec/blob/d46cd7f573a2c6a2399fcab2cde981330aa63f37/spec/core/data_structures.md#blockid

Default implementation is an empty Id as defined by the Go implementation in https://github.com/tendermint/tendermint/blob/1635d1339c73ae6a82e062cd2dc7191b029efa14/types/block.go#L1204.

If the Hash is empty in BlockId, the BlockId should be empty (encoded to None). This is implemented outside of this struct. Use the Default trait to check for an empty BlockId. See: https://github.com/informalsystems/tendermint-rs/issues/663

Fields

hash: Hash

The block’s main hash is the Merkle root of all the fields in the block header.

part_set_header: PartSetHeader

Parts header (if available) is used for secure gossipping of the block during consensus. It is the Merkle root of the complete serialized block cut into parts.

PartSet is used to split a byteslice of data into parts (pieces) for transmission. By splitting data into smaller parts and computing a Merkle root hash on the list, you can verify that a part is legitimately part of the complete data, and the part can be forwarded to other peers before all the parts are known. In short, it’s a fast way to propagate a large file over a gossip network.

PartSetHeader in protobuf is defined as never nil using the gogoproto annotations. This does not translate to Rust, but we can indicate this in the domain type.
