Struct StreamCheckpoint 

pub struct StreamCheckpoint {
    pub cursor: Vec<u8>,
    pub previous_cursor: Vec<u8>,
    pub snapshot_complete: bool,
    pub page: Option<PageInfo>,
}

Fields

cursor: Vec<u8>

The first checkpoint commits the staged snapshot. Later checkpoints commit a bounded batch of typed upserts/removals. Only committed cursors may resume.

previous_cursor: Vec<u8>

Empty for a replacement snapshot; otherwise the last committed cursor.

snapshot_complete: bool

page: Option<PageInfo>
