Actix Webfinger

A library to aid in resolving and providing webfinger objects with the Actix Web web framework.

• Read the documentation on docs.rs
• Find the crate on crates.io
• Hit me up on Mastodon

The main functionality this crate provides is through the Webfinger::fetch method for Actix Web-based clients, and the Resolver<S> trait for Actix Web-based servers.

Usage

First, add Actix Webfinger as a dependency

[dependencies]
actix = "0.10.0-alpha.1"
actix-web = "3.0.0-alpha.1"
actix-webfinger = "0.3.0-alpha.5"

Then use it in your application

Client Example

use actix_web::client::Client;
use actix_webfinger::Webfinger;
use std::error::Error;

#[actix_rt::main]
async fn main() -> Result<(), Box<dyn Error>> {
    let client = Client::default();
    let wf = Webfinger::fetch(&client, "asonix@asonix.dog", "localhost:8000", false).await?;

    println!("asonix's webfinger:\n{:#?}", wf);
    Ok(())
}

Server Example

use actix_web::{web::Data, App, HttpServer};
use actix_webfinger::{Resolver, Webfinger};
use std::{error::Error, future::Future, pin::Pin};

#[derive(Clone, Debug)]
pub struct MyState {
    domain: String,
}

pub struct MyResolver;

impl Resolver for MyResolver {
    type State = Data<MyState>;
    type Error = actix_web::error::JsonPayloadError;

    fn find(
        account: &str,
        domain: &str,
        state: &Data<MyState>,
    ) -> Pin<Box<dyn Future<Output = Result<Option<Webfinger>, Self::Error>>>> {
        let w = if domain == state.domain {
            Some(Webfinger::new(&format!("{}@{}", account, domain)))
        } else {
            None
        };

        Box::pin(async move { Ok(w) })
    }
}

#[actix_rt::main]
async fn main() -> Result<(), Box<dyn Error>> {
    HttpServer::new(|| {
        App::new()
            .data(MyState {
                domain: "asonix.dog".to_owned(),
            })
            .service(actix_webfinger::resource::<_, MyResolver>())
    })
    .bind("127.0.0.1:8000")?
    .run()
    .await?;

    Ok(())
}
