Struct StatsVisitor 

pub struct StatsVisitor {
    pub article_count: u64,
    pub category_count: u64,
    pub link_count: u64,
    pub infobox_count: u64,
    pub reference_count: u64,
}

A visitor that collects counts only (low memory footprint).

Tracks aggregate statistics without storing individual articles. Useful for getting overview statistics of a snapshot.

Example

use wme_stream::{ArticleVisitor, StatsVisitor};
use serde_json::Value;

let mut visitor = StatsVisitor::new();

// Simulate visiting articles
for i in 0..100 {
    visitor.visit_article_start(i as u64, "Article");
    visitor.visit_category("Category:Test", "https://en.wikipedia.org/wiki/Category:Test");
    visitor.visit_link("Link", "https://en.wikipedia.org/wiki/Link");
    visitor.visit_article_end();
}

assert_eq!(visitor.article_count, 100);
assert_eq!(visitor.category_count, 100);
assert_eq!(visitor.link_count, 100);

Fields

article_count: u64

Total articles processed

category_count: u64

Total categories found

link_count: u64

Total links found

infobox_count: u64

Total infoboxes found

reference_count: u64

Total references found

Implementations

impl StatsVisitor

pub fn new() -> Self

Example

use wme_stream::StatsVisitor;

let visitor = StatsVisitor::new();
assert_eq!(visitor.article_count, 0);
assert_eq!(visitor.category_count, 0);
