The LINE Messaging API SDK for Rust makes it easy to develop bots using LINE Messaging API, and you can create a sample bot within minutes.
See the official API documentation for more information.

This library requires stable/beta Rust.
$ cargo add line-bot-sdk-rustExtract x-line-signature from the request header.
[dependencies.line-bot-sdk-rust]
version = "1.0.0"
features = ["rocket_support"]use line_bot_sdk_rust::support::rocket::Signature;
use rocket::{http::Status, post};
#[post("/callback", data = "<body>")]
async fn world(signature: Signature, body: String) -> (Status, &'static str) {
...
}[dependencies.line-bot-sdk-rust]
version = "1.0.0"
features = ["actix_support"]use actix_web::{post, web, Error, HttpResponse};
use line_bot_sdk_rust::support::actix::Signature;
#[post("/callback")]
async fn callback(signature: Signature, bytes: web::Bytes) -> Result<HttpResponse, Error> {
...
}use line_bot_sdk_rust::client::LINE;
use std::env;
fn main() {
let access_token: &str =
&env::var("LINE_CHANNEL_ACCESS_TOKEN").expect("Failed to get LINE_CHANNEL_ACCESS_TOKEN");
let line = LINE::new(access_token.to_string());
}The LINE Messaging API uses the JSON data format.
Example. Parse body (&str) into Result<CallbackRequest, serde_json::Error>.
let request: Result<CallbackRequest, serde_json::Error> = serde_json::from_str(body);match request {
Err(err) => {
// error handling
},
Ok(req) => {
for e in req.events {
// Processing for various events
}
}
