Struct StreamToken 

pub struct StreamToken {
    pub stream_id: i64,
    pub after_event: bool,
}

A parsed pagination position — see the module doc.

A t{stream_id} token (or a bare integer) sits ON event stream_id: a backward page starts strictly before it, a forward page strictly after it. A sync token s{stream_id}_{typing_gen} (a /sync next_batch or prev_batch) sits AFTER event stream_id — that event was already delivered — so a backward page from it must still include that event. The typing half of a sync token is irrelevant to history and is ignored.

Fields

stream_id: i64

after_event: bool

Implementations

impl StreamToken

pub fn backward_bound(self) -> i64

The exclusive upper bound of a page that walks backward from this position: events with stream_id < bound.

pub fn forward_bound(self) -> i64

The exclusive lower bound of a page that walks forward from this position: events with stream_id > bound.

pub fn to_bound(self, dir: Direction) -> i64

The to= boundary of a page walking dir: the far end a page must not cross. It is the position’s bound as seen from the opposite walk direction, since to is approached rather than left.
