⚡rustygram

⚡rustygram is a minimal and blazing fast telegram notification framework using Rust. Abstracts away the Telegram API complexity so your app doesn't have to worry about the underlying implementation.

Highlights

• Easily integrate rustygram into your rust application to quickly send messages to Telegram bots, groups, and channels.

• Send asynchronous notifications in a reliable way.

API overview

• create_bot - create a bot instance consistsing of Telegram's bot token, and target chat_id
• send_message - call Telegram bot's API sendMessage to send message asynchronously

Examples

Send in simple way

fn main() {
 let instance = rustygram::create_bot("123456:123456", "-1000000");
 if let Err(_) = rustygram::send_message(&instance, "Hello world", None) {
  // error handling here...
 }
}

Send in MarkdownV2 or HTML style message

Send message in MarkdownV2

use rustygram::types::{SendMessageOption, SendMessageParseMode};

fn main() {
 let instance = rustygram::create_bot("16", "-1s00");
 let option = SendMessageOption { parse_mode: Some(SendMessageParseMode::MarkdownV2) };

 // note on two spaces at the end of the line for a new line in markdown
 if let Err(_) = rustygram::send_message(&instance,
r#"__Hello world__
`Tap to copy this text`
Visit my [website](https://yong-kang.super.site/)"#, Some(option)) {
  // error handling here...
 }
}

Send messsage in HTML

use rustygram::types::{SendMessageOption, SendMessageParseMode};

fn main() {
 let instance = rustygram::create_instance("189:blablabla", "-10");
 let option = SendMessageOption { parse_mode: Some(SendMessageParseMode::HTML) };

 if let Err(_) = rustygram::send_message(&instance,
r#"<u>Hello world</u>
<code>Tap to copy this text</code>
Visit my <a href="https://yong-kang.super.site/">website</a>"#, Some(option)) {
  // error handling here...
 }
}

Setting up and testing it as a class

• Check out example.rs where there is a concrete example with tests

Sending CSV file

use rustygram::types::{SendMessageOption, SendMessageParseMode};

fn main() {
  let instance = rustygram::create_bot("189:blablabla", "-10");
  let option = SendMessageOption { parse_mode: Some(SendMessageParseMode::MarkdownV2) };

  if let Err(_) = rustygram::send_csv(&instance, "example.csv", Some(option)) {
    // error handling here...
  }
}
```

- Refer to tests.rs for more reference on how to send a CSV file

## Setting up your environment

1. [Download Rust](http://rustup.rs/).
2. Create a new bot using [@Botfather](https://t.me/botfather) to get a token in the format `189:blablabla`.
3. Initialise the `BOT_TOKEN` environmental variable to your token:

```bash
# Unix-like
$ export BOT_TOKEN=<Your token here>

# Windows command line
$ set BOT_TOKEN=<Your token here>

# Windows PowerShell
$ $env:BOT_TOKEN=<Your token here>

4. Make sure that your Rust compiler is up to date (rustygram currently requires rustc at least version 1.68):

# If you're using stable
$ rustup update stable
$ rustup override set stable

# If you're using nightly
$ rustup update nightly
$ rustup override set nightly

5. Run cargo new my_bot, enter the directory and put these lines into your Cargo.toml:

[dependencies]
rustygram = "0.1"
log = "0.4"
pretty_env_logger = "0.4"
tokio = { version =  "1.8", features = ["rt-multi-thread", "macros"] }

Tests

You can test by define the following two environment variables

• TEST_BOT_TOKEN - telegram bot's token
• TEST_CHAT_ID - telegram bot's chat id

then execute

cargo test

some tests will send a single, or multiple messages to a specified chat id on behalf of such telegram bot. Please take a look at src/tests.rs.

Note

You can utilize this telegram bot @username_to_id_bot to get your telegram channel's chat_id.

This project is heavily inspired by teloxide. However it is not a fork of teloxide, but a complete rewrite in order to make it more minimal and faster for the use case of sending notifications on telegram.

The simplistic design is inspired by rustelebot but with more modular and extensible design, also changing the underlying libraries used to be more modern.
