Struct CqlRowStream 

pub struct CqlRowStream {
    pub columns: Vec<CqlColumn>,
    pub rows: Pin<Box<dyn Stream<Item = Result<CqlRow>> + Send>>,
}

A streaming result set that yields rows lazily from the database.

Rows are fetched page-by-page from the server as they are consumed, keeping memory usage bounded for large result sets.

Fields

columns: Vec<CqlColumn>

Column metadata (available immediately after query starts).

rows: Pin<Box<dyn Stream<Item = Result<CqlRow>> + Send>>

The underlying async stream of rows.
