Struct SaveWait 

pub struct SaveWait { /* private fields */ }

A future that resolves once a save has run, or once a staged write that held an object has gone, whichever it was handed out for.

It holds no lock and borrows nothing, so it can be awaited after the database guard is dropped.

Implementations

impl SaveWait

pub fn is_ready(&self) -> bool

Whether the wait is already over.

pub fn block(&self)

Block this thread until the wait is over, for a caller that waits off its async runtime, such as on Tokio’s blocking pool.

fn clone(&self) -> Self
