Module two_phase 

Two-phase stepping utilities inspired by FlameGPU2.

FlameGPU2’s stepping model separates agent computation into distinct phases via the layer system:

1. Output phase: agents write messages (no reading)
2. Spatial index build: messages are spatially sorted (PBM construction)
3. Input phase: agents read messages and update state

This module provides helper functions (two_phase_brute_force, two_phase_spatial_2d, two_phase_spatial_3d) that automate this pattern for use with StandardModel and spatial messaging.

Structs

TwoPhaseResult

Result of a two-phase step.

Execute a two-phase step using brute-force messaging.

two_phase_spatial_2d
