Slack Messaging

This is a library for Rust to support building Slack Block Kit messages. Using this, you can build any messages in type-safe way like following.

use slack_messaging::{mrkdwn, plain_text,Message};use slack_messaging::blocks::{elements::Button,Actions,Section};use std::error::Error;#[tokio::main]asyncfnmain() -> Result<(),Box<dynError>>{let message = Message::builder().block(Section::builder().text(mrkdwn!("You have a new request:\n*<fakeLink.toEmployeeProfile.com|Fred Enriquez - New device request>*")?).build()?
).block(Section::builder().field(mrkdwn!("*Type:*\nComputer (laptop)")?).field(mrkdwn!("*When:*\nSubmitted Aug 10")?).build()?
).block(Actions::builder().element(Button::builder().text(plain_text!("Approve")?).value("approve").primary().build()?
).element(Button::builder().text(plain_text!("Deny")?).value("deny").danger().build()?
).build()?
).build()?;let req = reqwest::Client::new().post("https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX").json(&message);ifletErr(err) = req.send().await{eprintln!("{err}");}Ok(())}

The message payload of the above example is following.

{
"blocks": [
{
"type": "section",
"text": {
"type": "mrkdwn",
"text": "You have a new request:\n*<fakeLink.toEmployeeProfile.com|Fred Enriquez - New device request>*"
}
},
{
"type": "section",
"fields": [
{
"type": "mrkdwn",
"text": "*Type:*\nComputer (laptop)"
},
{
"type": "mrkdwn",
"text": "*When:*\nSubmitted Aug 10"
}
]
},
{
"type": "actions",
"elements": [
{
"type": "button",
"text": {
"type": "plain_text",
"text": "Approve"
},
"value": "approve",
"style": "primary"
},
{
"type": "button",
"text": {
"type": "plain_text",
"text": "Deny"
},
"value": "deny",
"style": "danger"
}
]
}
]
}
