Result of Eisenstein constraint snap

Fields

dodecet: u16

The 12-bit dodecet encoding the full constraint state

snap_a: i32

Nearest Eisenstein integer (a, b) where a + bω is the snap point

snap_b: i32

error: f64

Snap error (distance from input to snap point)

error_normalized: f64

Error normalized to covering radius [0, 1]

error_level: u8

Error quantized to 16 levels (nibble 2)

angle_level: u8

Azimuthal angle quantized to 16 levels (nibble 1)

chamber: u8

Weyl chamber index 0-5

parity: i8

Parity: +1 for even chambers, -1 for odd

is_safe: bool

Whether the point is within the safe zone (error < ρ/2)

Implementations

impl SnapResult

pub fn to_hex(&self) -> String

Format dodecet as hex string (3 chars)

pub fn parity_str(&self) -> &'static str

Get parity as string

pub fn funnel_position(&self) -> f64

Deadband funnel position: √(error/ρ) 0.0 = on snap, 1.0 = at boundary Square-root because CDF = πr²/A → r = √(A·P/π)

pub fn precision_feeling(&self) -> f64

Precision feeling Φ = 1/δ where δ is the deadband Higher Φ = more constrained

pub fn decode_dodecet(dodecet: u16) -> (u8, u8, u8, bool)

Decode dodecet back to components

pub fn cdf_below(&self) -> f64

CDF prediction: P(d < r) = πr²/A Given this error level, what fraction of points have LESS error?
