Struct DecomposeOptions 

pub struct DecomposeOptions {
    pub allow_steiner: bool,
    pub max_rotation_attempts: usize,
    pub collect_trace: bool,
    pub minimize_parts: bool,
}

Options for the decompose() cascade.

Fields

allow_steiner: bool

If true, Bayazit may introduce Steiner points at edge intersections. If false, only original vertices are used (exact_vertex_partition preferred).

max_rotation_attempts: usize

Number of ring rotation attempts if initial decomposition fails. Default: vertex_count.

collect_trace: bool

minimize_parts: bool

If false (default) — cascade mode: try ExactPartition → Bayazit → EarClipMerge in order and return the first strategy that passes validation. This minimizes Steiner-point pollution and keeps the on-chain client behaviour deterministic.

If true — run every strategy across every rotation that is attempted, collect all validated candidates, and return the one with the fewest parts. Ties are broken by: fewer Steiner points, then earlier rotation, then strategy preference (Exact > Bayazit > EarClip). Strictly more work than cascade mode; intended for demos, tooling, and research where “absolute minimum parts” matters more than cascade determinism.
