⚡ Bolt: [Zero-Allocation ExecutionNode State Comparison] - #120
Conversation
…mparison In `phase_composite_reevaluation`, multiple `Vec` allocations were used to snapshot and compare `ExecutionNode` states before, during, and after block execution. This replaces the allocations with a zero-allocation `states_differ` helper that compares slice lengths and uses `.zip().any()` to quickly short-circuit on changes, reducing memory overhead on the execution hot path.

This replaces the allocations with a zero-allocation `states_differ` helper that compares slice lengths and uses `.zip().any()` to quickly short-circuit on changes, reducing memory overhead on the execution hot path. Also fixed a clippy warning `clippy::manual_is_variant_and` in `orch8-push/src/fcm.rs`. Co-authored-by: ovasylenko <3797513+ovasylenko@users.noreply.github.com>

💡 What: Replaced
Vec<(ExecutionNodeId, NodeState)>allocations inphase_composite_reevaluationwith a zero-allocationstates_differhelper function.🎯 Why: To reduce unnecessary memory allocations and hashing overhead on the evaluation hot path when comparing execution tree states.
📊 Impact: Eliminates multiple heap allocations per composite node tick, improving throughput and reducing memory pressure during heavy workloads.
