Struct CursorData 

pub struct CursorData {
    pub limit: usize,
    pub cursor: i64,
}

Opaque pagination cursor carrying the page size and last-seen id.

Encoded as base64 JSON by CursorData::encode; decoded back by CursorData::decode, which returns None for malformed input.

Fields

limit: usize

Page size the cursor was issued for.

cursor: i64

Last-seen row id; the next page continues after (or before) it.
