Unique semantics are builtin uniforms passed by the shader runtime that are always available.

Variants

MVP = 0

The Model View Projection matrix for the frame.

Output = 1

The viewport size of the current pass.

FinalViewport = 2

The viewport size of the final pass.

FrameCount = 3

The frame count, possibly with shader-defined modulo.

FrameDirection = 4

The direction in time where frames are rendered

FrameTimeDelta = 5

The time delta between the previous frame and the current frame.

OriginalFPS = 6

The original frames per second for the underlying content

Rotation = 7

The rotation index (0 = 0deg, 1 = 90deg, 2 = 180deg, 3 = 270deg)

OriginalAspect = 8

The original aspect ratio

OriginalAspectRotated = 9

The original aspect ratio, if rotated.

TotalSubFrames = 10

Total number of subframes.

CurrentSubFrame = 11

The current subframe (default 1)

FloatParameter = 12

A user defined float parameter.

Implementations

impl UniqueSemantics

pub const fn semantics(self) -> Semantic<UniqueSemantics, ()>

Produce a Semantic for this UniqueSemantics.

pub const fn binding_type(&self) -> UniformType

Get the type of the uniform when bound.

pub const fn as_str(&self) -> &'static str

Get the name of the semantic as a string.

Trait Implementations

impl Clone for UniqueSemantics

fn clone(&self) -> UniqueSemantics

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UniqueSemantics

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

Formats the value using the given formatter.

impl Display for UniqueSemantics

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

Formats the value using the given formatter.

impl From<UniqueSemantics> for UniformBinding

fn from(value: UniqueSemantics) -> Self

Converts to this type from the input type.

impl Hash for UniqueSemantics

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 UniqueSemantics

fn cmp(&self, other: &UniqueSemantics) -> 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 UniqueSemantics

fn eq(&self, other: &UniqueSemantics) -> 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 UniqueSemantics

fn partial_cmp(&self, other: &UniqueSemantics) -> 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.
