Enum Reference 

pub enum Reference {
    Optimistic,
    NearFinal,
    Final,
    AtBlock(u64),
    AtBlockHash(CryptoHash),
}

A reference to a specific block. This type is used to specify the block for most queries.

It represents the finality of a transaction or block in which transaction is included in. For more info go to the NEAR finality docs.

Variants

Optimistic

Optimistic finality. The latest block recorded on the node that responded to our query (<1 second delay after the transaction is submitted).

NearFinal

Near-final finality. Similarly to Final finality, but delay should be roughly 1 second.

Final

Final finality. The block that has been validated on at least 66% of the nodes in the network. (At max, should be 2 second delay after the transaction is submitted.)

AtBlock(u64)

Reference to a specific block.

AtBlockHash(CryptoHash)

Reference to a specific block hash.
