Struct ReplayEngine 

pub struct ReplayEngine { /* private fields */ }

ReplayEngine reconstructs the execution state from a Timeline. It creates a “virtual” cursor that moves through the circuit based on recorded events.

Implementations

impl ReplayEngine

pub fn new(timeline: Timeline) -> Self

pub fn next_step(&mut self) -> Option<ReplayFrame>

Advance the replay by one step. Returns the current frame or None if finished.

pub fn reset(&mut self)

Reset replay to start

pub fn fast_forward_to_end(&mut self) -> Option<ReplayFrame>

Fast-forwards the replay cursor to the end, returning the final known frame. This is a O(1) operation since it just jumps to the end of the timeline array.

pub fn fast_forward_to_active(&mut self) -> Option<ReplayFrame>

Fast-forwards the replay cursor to the last active (entered but not exited) node. This is useful for active intervention where we want to resume execution at the exact stalled point.
