Struct AsyncSnapshot 

pub struct AsyncSnapshot<T> {
    pub state: ConnectionState,
    pub data: Option<T>,
}

What a component knows of a piece of work that finishes later: where it has got to, and the last value it gave, if any — the reference’s AsyncSnapshot.

An error is a value like any other: work that can fail gives a Result.

Fields

state: ConnectionState

Where the work has got to.

data: Option<T>

The last value it gave: a future’s result once it is done, a stream’s latest.
