Enum lidrs::io::ies::phot_type::IesPhotometryType

#[repr(usize)]
pub enum IesPhotometryType {
    TypeC,
    TypeB,
    TypeA,
}

Determine the type of photometry contained within the file. A brief description of each type can be found on Owen Ransens web page here: http://www.ransen.com/photometric/Type-A-Type-B-Type-C-IES-IESNA-Photometry-Files.htm

Variants

TypeC

This type is generally used for internal lighting and use the C-Gamma system for measurements. This type of file is by far the most popular. In this system, gamma = 0 corresponds to downwards. The C-angle is the anti-clockwise angle, around the gamma = 0 axis.

TypeB

This type is used for floodlights, and the photometry is expressed in a VH system. In this system, the lights are expressed as a hemisphere of intensities.

TypeA

This type is used for car headlights. In this case, the polar axis corresponds to the major axis of the luminaire, i.e. the direction that the light is pointing.

Trait Implementations

impl Clone for IesPhotometryType

fn clone(&self) -> IesPhotometryType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IesPhotometryType

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

Formats the value using the given formatter.

impl Default for IesPhotometryType

fn default() -> Self

I will return Type C by default, as it permits the most leway.

impl PartialEq<IesPhotometryType> for IesPhotometryType

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<usize> for IesPhotometryType

type Error = TryFromPrimitiveError<IesPhotometryType>

The type returned in the event of a conversion error.

fn try_from(number: usize) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for IesPhotometryType

type Primitive = usize

const NAME: &'static str = _

fn try_from_primitive(
    number: Self::Primitive
) -> Result<Self, TryFromPrimitiveError<Self>>
