Struct Page 

pub struct Page {
    pub offset: usize,
    pub limit: usize,
    pub total: Option<u64>,
    pub has_more: bool,
}

Pagination info for a query result.

The default reply costs one page: the server fetches limit + 1 rows and answers has_more exactly from the probe row, never counting the rest. total is present only when the request set want_total, which runs a real COUNT(*) over the filter (unbounded work on a large index). A caller that never asked cannot misread a page-bounded number as a count: there is no number.

Fields

offset: usize

limit: usize

total: Option<u64>

has_more: bool

Implementations

impl Page

pub fn at_least(&self, rows_on_page: usize) -> usize

Rows known to exist so far: the position one past this page’s last row. A cheap display lower bound ("1234+ rows"), paired with Self::has_more for the trailing +.

pub fn total_pages(&self) -> Option<u64>

Pages implied by the exact total, when one was requested. None without want_total or with a zero limit (page math is undefined without a page size).
