Struct LightType 

pub struct LightType(/* private fields */);

[docs.microsoft.com] D3DLIGHTTYPE

Defines the light type.

Directional lights are slightly faster than point light sources, but point lights look a little better. Spotlights offer interesting visual effects but are computationally time-consuming.

Implementations

impl LightType

pub const fn from_unchecked(d3d: D3DLIGHTTYPE) -> Self

Convert from an underlying winapi D3D... type. This is probably safe… probably…

pub const fn into(self) -> D3DLIGHTTYPE

Convert back into an underlying winapi D3D... type.

impl LightType

pub const Point: LightType

Light is a point source. The light has a position in space and radiates light in all directions.

pub const Spot: LightType

Light is a spotlight source. This light is like a point light, except that the illumination is limited to a cone. This light type has a direction and several other parameters that determine the shape of the cone it produces. For information about these parameters, see the Light structure.

pub const Directional: LightType

Light is a directional light source. This is equivalent to using a point light source at an infinite distance.

Trait Implementations

impl Clone for LightType

fn clone(&self) -> LightType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LightType

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

Formats the value using the given formatter.

impl Default for LightType

fn default() -> Self

Returns the “default value” for a type.

impl From<LightType> for D3DLIGHTTYPE

fn from(value: LightType) -> Self

Converts to this type from the input type.

impl Hash for LightType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for LightType

fn cmp(&self, other: &LightType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LightType

fn eq(&self, other: &LightType) -> 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 PartialOrd for LightType

fn partial_cmp(&self, other: &LightType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
