Struct Notice 

#[non_exhaustive]
pub struct Notice {
    pub through: Cursor,
}

One StreamData frame of an open subscription: new steps may exist up to through, the newest committed cursor.

Notices are coalesced (at most four a second), and one may cover many steps or none the caller may see. It carries no rows; read them with usage.steps.read. Unknown members are ignored.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

through: Cursor
