github crates.io docs.rs ci status

This is a Slack library for Rust that I'm working on, inspired by slack-go/slack.
It supports SocketMode, Event API, and WEB API.

⚠️ This crate is still under development. If you have any feature requests or bugs, please create an issue! 👋

Usage

Add this to your Cargo.toml:

[dependencies]
slack-rust = "0.0.1-alpha"
use slack::chat::post_message::{post_message, PostMessageRequest};
use slack::http_client::default_client;
use slack_rust as slack;
use std::env;

#[async_std::main]
async fn main() {
    let slack_bot_token =
        env::var("SLACK_BOT_TOKEN").unwrap_or_else(|_| panic!("slack bot token is not set."));

    let slack_api_client = default_client();
    let param = PostMessageRequest {
        channel: "channel_id".to_string(),
        text: Some("Hello world!!".to_string()),
        ..Default::default()
    };

    let response = post_message(&slack_api_client, &param, &slack_bot_token)
        .await
        .expect("api call error");
    println!("{:?}", response);
}

Builder

use slack::attachment::attachment::Attachment;
use slack::chat::post_message::{post_message, PostMessageRequest};
use slack::http_client::default_client;
use slack_rust as slack;
use std::env;

#[async_std::main]

    let slack_bot_token =
        env::var("SLACK_BOT_TOKEN").unwrap_or_else(|_| panic!("slack bot token is not set."));
    let slack_channel_id =
        env::var("SLACK_CHANNEL_ID").unwrap_or_else(|_| panic!("slack channel id is not set."));

    let slack_api_client = default_client();

    let attachments = vec![Attachment::builder()
        .color("#36a64f".to_string())

        .title("slack_rust_example".to_string())
        .build()];
    let param = PostMessageRequest::builder(slack_channel_id)
