WebSocketRuntime

lightyear::websocket::prelude

Struct WebSocketRuntime 

Source 
pub struct WebSocketRuntime { /* private fields */ }
Available on crate feature websocket only.
Expand description

Provides a platform-agnostic way to spawn futures for driving the WebSocket IO layer.

Using WebSocket sessions requires spawning tasks on an async runtime. However, which runtime to use exactly, and how that runtime is provided, is target-dependent. This resource exists to provide a platform-agnostic way of spawning these tasks.

§Platforms

§Native

On a native target, this holds a handle to a tokio runtime, because tokio-tungstenite only supports this async runtime.

Use the Default impl to create and leak a new tokio runtime, and use that as the WebSocketRuntime handle.

If you already have a runtime handle, you can use WebSocketRuntime::from(handle) to create a runtime from that handle.

§WASM

On a WASM target, this uses wasm-bindgen-futures to spawn the future via wasm-bindgen.

Use the Default impl to create a new WebSocketRuntime on WASM.

Implementations§

Source§

impl WebSocketRuntime

Source

pub fn spawn_on_self<F>(&self, future: F)
where F: Future<Output = ()> + Send + 'static,

Spawns a future on the task runtime self.

If you are already in a task context, use the spawn function on your platform (i.e. tokio::spawn) to avoid having to pass around WebSocketRuntime.
