dtek-parse

A Rust library and set of bots for parsing power outage schedules from the DTEK website.

What's included

Quick example

#![allow(unused)]
fn main() {
use dtek_parse::DTEKParser;

let mut parser = DTEKParser::new()?;

// All groups in one HTTP request
let schedules = parser.get_all_schedules()?;
for (group, data) in &schedules {
    println!("{}: {} days", group, data.schedules.len());
}
}

Key design decisions

• Single HTTP request — get_all_schedules() fetches every group at once.
• curl-impersonate — bypasses Incapsula bot protection without a real browser.
• Shared DB — optional SCHEDULE_DB_URL lets one dtek-schedule-service process serve both bots, eliminating duplicate requests.
• In-memory cache — both bots cache schedules for CACHE_DURATION_MINUTES (default 30 min) and only hit DTEK (or the shared DB) on a miss.
• Persistent change detection — the Telegram bot saves schedule snapshots to SQLite so change notifications survive restarts.
