Struct RangeCursor 

pub struct RangeCursor {
    pub last_key: Option<CowVec<u8>>,
    pub exhausted: bool,
}

Cursor state for streaming range queries.

Tracks position within a range scan, enabling efficient continuation across multiple batches without re-scanning from the beginning.

Fields

last_key: Option<CowVec<u8>>

Last key seen in the previous batch (for Bound::Excluded continuation)

exhausted: bool

Whether this stream is exhausted
