Struct pleingres::Handle

source ·

pub struct Handle<R> { /* private fields */ }

Expand description

A handle to a database connection that has been spawn to an event loop. This is actually a synchronization channel.

Implementations

source

impl<R: Request + HandleRow> Handle<R>

source

pub fn send_request<F>(&self, r: F) -> SendRequest<R>where
R: From<F>,

Send a request to this handle. Methods from the Request and HandleRow traits will be called as needed.

The request will be sent through a futures::mpsc channel, along with a futures::channel::oneshot channel to “wait” the result on.

source

pub fn shutdown(&self) -> ShutdownFuture<R>
