# language-server

A library to implement asynchronous language servers in Rust. It features

- Full server and client support of the

  [Language Server Protocol 3.15](https://microsoft.github.io/language-server-protocol/specifications/specification-3-15/).

- Independent of the underlying transport layer and the used async executor.

## Example

A simple language server using the [Tokio](https://tokio.rs/) runtime:

```rust

use async_executors::TokioTp;

use language_server::{async_trait::async_trait, types::*, *};

use std::{convert::TryFrom, sync::Arc};

use tokio_util::compat::*;

struct Server;

#[async_trait]

impl LanguageServer for Server {

    async fn initialize(

        &self,

        _params: InitializeParams,

        _client: Arc,

    ) -> Result {

        Ok(InitializeResult::default())

    }

    async fn initialized(&self, _params: InitializedParams, client: Arc) {

        let params = ShowMessageParams {

            typ: MessageType::Info,

            message: "Hello World!".to_owned(),

        };

        client.show_message(params).await;

    }

}

fn main() {

    let executor = TokioTp::try_from(&mut tokio::runtime::Builder::new())

        .expect("failed to create thread pool");

    executor.block_on(

        LanguageService::builder()

            .server(Arc::new(Server))

            .input(tokio::io::stdin().compat())

            .output(tokio::io::stdout().compat_write())

            .executor(executor.clone())

            .build()

            .listen(),

    );

}

```
