Struct DirectedTurnWindow 

pub struct DirectedTurnWindow {
    pub expected_member: BridgeMemberIncarnation,
    pub subscription: EventStream,
    pub window_start: u64,
    pub generation: u64,
    pub fence_token: u64,
    pub input_id: String,
    pub tracking: DirectedTurnTracking,
}

Pre-accept event window for a directed turn (DEC-P6E-16’s atomicity letter: the subscription exists BEFORE accept_input_with_completion runs, so no terminal can slip between accept and watch).

Fields

expected_member: BridgeMemberIncarnation

Full host residency captured with the durable Pending reservation. Every later cancel/admit/record uses this tuple rather than re-deriving authority from a possibly replaced session projection.

subscription: EventStream

Live session-events subscription opened before acceptance.

window_start: u64

Durable watermark at open (+1 = first seq that can belong to this window). The terminal_seq binder scans forward from here.

generation: u64

Member generation at open.

fence_token: u64

Materialization fence paired with generation.

input_id: String

Exact directed-turn input id reserved before runtime acceptance.

tracking: DirectedTurnTracking

Whether the host persisted/replayed Pending or found an already terminal exact key. Terminal replay needs no watcher.

Implementations

impl DirectedTurnWindow

pub fn admission_request(&self) -> DirectedTurnAdmissionRequest

Snapshot the exact durable reservation facts used by the final admission revalidation. The live subscription remains owned by this window for the terminal watcher.

impl Debug for DirectedTurnWindow

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
