Struct DocumentPageSource 

pub struct DocumentPageSource {
    pub collection: QualifiedCollection,
    pub filters: Vec<u8>,
    pub system_as_of_ms: Option<i64>,
    pub offset: usize,
    pub limit: Option<usize>,
    pub column_map: Vec<u8>,
}

A plain document scan source, read page by page.

Fields

collection: QualifiedCollection

filters: Vec<u8>

Serialized Vec<ScanFilter>: the WHERE clause, ANDed with the collection’s read policy by the RLS pass.

system_as_of_ms: Option<i64>

FOR SYSTEM_TIME AS OF cut, in epoch milliseconds. None reads the current version.

offset: usize

Matching rows skipped before the first row is read.

limit: Option<usize>

Matching rows read after the offset. None reads every matching row.

column_map: Vec<u8>

zerompk Vec<ComputedColumn>: one entry per target column, its alias the target column and its expression the source-row expression. Empty passes each source row through unchanged.
