Implementations

impl LuminousShape

pub fn from_dimensions(width: f64, length: f64, height: f64) -> Self

Determine shape from width, length, height values.

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

Get description of the shape.

Trait Implementations

impl Clone for LuminousShape

fn clone(&self) -> LuminousShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LuminousShape

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

Formats the value using the given formatter.

impl Default for LuminousShape

fn default() -> LuminousShape

Returns the “default value” for a type.

impl PartialEq for LuminousShape

fn eq(&self, other: &LuminousShape) -> 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.
