Struct LiveState 

pub struct LiveState {
    pub unseen: Unseen,
    pub composer: Composer,
    attached: HashMap<SessionSlot, usize>,
    seen_failed: HashMap<SessionSlot, SystemTime>,
}

What the stream has said, as one render reads it. A render takes this rather than the lock: the guard is not Send, and a handler that held it across its own awaits could not be one.

Fields

unseen: Unseen

composer: Composer

attached: HashMap<SessionSlot, usize>

The seats a page is open on, by how many connections are showing them, and when each seat was last shown: together these answer whether a failure on it is the reader’s to see, which the home read filters rows with.

seen_failed: HashMap<SessionSlot, SystemTime>

Implementations

impl LiveState

pub fn failed_mark( &self, slot: &SessionSlot, at: SystemTime, ) -> Option<SystemTime>

The failure instant the rail should draw for slot, or None when there is no failure to mark: the seat is being shown (some connection is watching it fail), or it has been shown since the failure landed.

Trait Implementations

impl Default for LiveState

fn default() -> Self
