Enum From 

pub enum From {
    NoSuchValue(Path),
    Denied(Path),
    Unsubscribed(Id),
    Subscribed(Path, Id, Value),
    Update(Id, Value),
    Heartbeat,
    WriteResult(Id, Value, WriteId),
}

Variants

NoSuchValue(Path)

The requested subscription to Path cannot be completed because it doesn’t exist

Denied(Path)

Permission to subscribe to the specified path is denied.

Unsubscribed(Id)

You have been unsubscriped from Path. This can be the result of an Unsubscribe message, or it may be sent unsolicited, in the case the value is no longer published, or the publisher is in the process of shutting down.

Subscribed(Path, Id, Value)

Update(Id, Value)

A value update to Id

Heartbeat

Indicates that the publisher is idle, but still functioning correctly.

WriteResult(Id, Value, WriteId)

Indicates the result of a write request

impl PartialEq for From

fn eq(&self, other: &From) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
