tests/mock/mod.rs emulates the device's TCP protocol (ping, get_name, get_total_record_count, get_record_bytes), grounded in the reverse engineering notes at https://nicolabelluti.me/posts/2024/05/studying-a-communication-protocol/, so tests/e2e.rs can exercise the real R701 client against it instead of needing a physical reader. Starts with one test (connect + ping); more scenarios (get_name, record streaming, error cases) to follow. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
A reverse-engineered library to communicate with the R701 by I.P.S. Informatica, written in Rust

Library Usage
-
Add the library to you project:
cargo add r701 --git https://git.nicolabelluti.me/nicolabelluti/r701.git -
Use the library in you project:
This library is async and built on tokio; add it to your own
[dependencies](e.g.tokio = { version = "1", features = ["rt-multi-thread", "macros"] }) to run the example below.use r701::R701; use tokio_stream::StreamExt; #[tokio::main] async fn main() { let r701 = R701::connect("127.0.0.1:5005").await.unwrap(); let mut record_stream = r701.into_record_iter().await.unwrap(); let mut id = 0; println!("No\tMchn\tEnNo\t\tName\t\tMode\tIOMd\tDateTime\t"); while let Some(record) = record_stream.next().await { let record = record.unwrap(); let name = match r701.get_name(record.employee_id).await.unwrap() { Some(Ok(name)) => name, Some(Err(error)) => String::from_utf8_lossy(error.as_bytes()).into_owned(), None => format!("user #{}", record.employee_id), }; println!( "{:0>6}\t{}\t{:0>9}\t{: <10}\t{}\t{}\t{}", id + 1, 1, record.employee_id, name, 35, record.clock as u8, record.datetime.format("%Y/%m/%d %H:%M:%S"), ); id += 1; } }
