Enum DisconnectBehavior 

pub enum DisconnectBehavior {
    Halt,
    ContinueWithout,
}

Controls how a P2PSession reacts when a remote peer’s automatic disconnect-timeout fires.

This setting governs ONLY the automatic timeout path. Explicit calls to P2PSession::disconnect_player always preserve the legacy halt-on-drop semantics regardless of this setting; explicit calls to P2PSession::remove_player always perform a graceful drop regardless of this setting. See those methods for details.

Defaults to DisconnectBehavior::Halt for back-compat with the legacy GGRS-style behavior. Set DisconnectBehavior::ContinueWithout via crate::SessionBuilder::with_disconnect_behavior to enable graceful peer drop on auto-timeout, where the session continues advancing for the remaining peers after a drop.

Example

use fortress_rollback::{Config, DisconnectBehavior, SessionBuilder};

// Continue the session for remaining peers after a drop, freezing the
// dropped peer's input at their last confirmed value.
let builder = SessionBuilder::<MyConfig>::new()
    .with_disconnect_behavior(DisconnectBehavior::ContinueWithout);

Variants

Halt

Halt the session: no further frames advance once any peer drops.

This is the legacy behavior inherited from GGRS. It is the default for back-compat: existing applications that do not opt into Self::ContinueWithout continue to observe the same session-stops-on-drop semantics.

ContinueWithout

Continue the session with the remaining peers.

The dropped peer’s input queue is frozen (it repeats their last confirmed input forever), and a crate::FortressEvent::PeerDropped event is emitted. Remaining peers keep advancing frames using the frozen input — the game layer decides how to handle the gameplay impact (AI takeover, pause, end the match, etc.).

Note: this setting governs only the automatic disconnect-timeout path. The legacy P2PSession::disconnect_player retains its original non-graceful semantics regardless of this setting; for an explicit graceful drop, use P2PSession::remove_player.

Trait Implementations

impl Clone for DisconnectBehavior

fn clone(&self) -> DisconnectBehavior

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DisconnectBehavior

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

Formats the value using the given formatter.

impl Default for DisconnectBehavior

fn default() -> DisconnectBehavior

Returns the “default value” for a type.

impl Display for DisconnectBehavior

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

Formats the value using the given formatter.

impl Hash for DisconnectBehavior

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for DisconnectBehavior

fn eq(&self, other: &DisconnectBehavior) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
