Enum State 

#[non_exhaustive]
pub enum State {
    Before(StateEvents),
    After(StateEvents),
}

Available on crate features client or server only.

State changes in a room.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Before(StateEvents)

The state changes between the previous sync and the start of the timeline.

To get the full list of state changes since the previous sync, the state events in Timeline must be added to these events to update the local state.

To get this variant, use_state_after must be set to false in the Request, which is the default.

After(StateEvents)

The state changes between the previous sync and the end of the timeline.

This contains the full list of state changes since the previous sync. State events in Timeline must be ignored to update the local state.

To get this variant, use_state_after must be set to true in the Request.
