Enum Symmetry 

pub enum Symmetry {
    None = 0,
    VerticalAxis = 1,
    PlaneC0C180 = 2,
    PlaneC90C270 = 3,
    BothPlanes = 4,
}

Symmetry indicator for the luminaire.

Defines how the luminous intensity distribution is symmetric, which affects how much data needs to be stored.

Variants

None = 0

No symmetry (Isym = 0) - full 360° data required

VerticalAxis = 1

Symmetry about the vertical axis (Isym = 1) - only 1 C-plane needed

PlaneC0C180 = 2

Symmetry to plane C0-C180 (Isym = 2) - half the C-planes needed

PlaneC90C270 = 3

Symmetry to plane C90-C270 (Isym = 3) - half the C-planes needed

BothPlanes = 4

Symmetry to both planes C0-C180 and C90-C270 (Isym = 4) - quarter C-planes needed

Implementations

impl Symmetry

pub fn from_int(value: i32) -> Result<Self>

Create from integer value.

pub fn as_int(&self) -> i32

Convert to integer value.

pub fn calc_mc(&self, nc: usize) -> usize

Calculate the actual number of C-planes needed based on symmetry.

This is the key optimization that reduces storage requirements:

• No symmetry: all Nc planes
• Vertical axis: 1 plane (360x reduction!)
• C0-C180: Nc/2 + 1 planes (2x reduction)
• C90-C270: Nc/2 + 1 planes (2x reduction)
• Both planes: Nc/4 + 1 planes (4x reduction)

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

Get human-readable description.

Trait Implementations

impl Clone for Symmetry

fn clone(&self) -> Symmetry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Symmetry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Symmetry

fn default() -> Symmetry

Returns the “default value” for a type.

impl PartialEq for Symmetry

fn eq(&self, other: &Symmetry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Symmetry

impl Eq for Symmetry

impl StructuralPartialEq for Symmetry
