Struct Stats 

pub struct Stats {
    pub blocks_total: usize,
    pub blocks_scanned: usize,
    pub rows_scanned: usize,
    pub rows_matched: usize,
    pub dropped_series: usize,
}

What a search cost, reported alongside the rows.

Not decoration. “How much did that cost” is the first question when a query is slow, and it is also what tells an agent its filter was too broad.

Fields

blocks_total: usize

blocks_scanned: usize

rows_scanned: usize

rows_matched: usize

Rows satisfying the whole query — window, terms and after — not rows on this page. limit cuts the page; this says how much there was to cut, so a caller can tell “my filter is right and I am reading page one of forty” from “my filter is wrong”.

dropped_series: usize

Series the metrics cap refused (series::bound); always zero on a record search, which has no such cap.

The counterpart to the per-series dropped_points, and here rather than in the response body because the response body is a JSON array with nowhere to hang a number that belongs to all of it. A chart with a series missing and no way to know it is the failure mode both of these exist to prevent.

Trait Implementations

impl Clone for Stats

fn clone(&self) -> Stats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Stats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Stats

fn default() -> Stats

Returns the “default value” for a type.
