Struct EmbeddedServer 

pub struct EmbeddedServer { /* private fields */ }

A bound loopback listener, not yet serving anything.

Implementations

impl EmbeddedServer

pub async fn bind() -> Result<Self, NativeError>

Bind 127.0.0.1 on a port the operating system chooses.

There is deliberately no bind_to(host, port). Every reason to want one — a fixed port for a bookmark, a LAN address for a second device — is a reason a packaged application should not have.

pub fn addr(&self) -> SocketAddr

The address that actually bound, port included.

pub fn port(&self) -> u16

The port the operating system assigned.

pub fn base_url(&self) -> String

Where to point the WebView.

127.0.0.1 rather than localhost: the name resolves to both stacks and a WebView that tried ::1 first would spend a timeout on every launch reaching a server that is not there. It is also the origin the document will be on, and an origin that is decided by a resolver is one that CSRF and the socket handshake’s origin check cannot rely on.

pub fn serve(self, router: Router) -> RunningServer

Start serving router, on a task.

Returns immediately. The listener was bound by bind, so the port in base_url is already accepting.
