Struct Cursor 

pub struct Cursor {
    pub block_number: u64,
    pub transaction_index: u32,
    pub log_index: u32,
    pub batch_index: Option<u32>,
    pub timestamp: Option<u64>,
    pub values: BTreeMap<String, Value>,
}

A cursor is a sortable unique identifier for a specific log entry. Used to paginate through query results efficiently.

Fields

batch_index: Option<u32>

timestamp: Option<u64>

values: BTreeMap<String, Value>
