Enum TextureSemantics

#[repr(i32)]
pub enum TextureSemantics {
    Original = 0,
    Source = 1,
    OriginalHistory = 2,
    PassOutput = 3,
    PassFeedback = 4,
    User = 5,
}

Texture semantics relate to input or output textures.

Texture semantics are used to relate both texture samplers and *Size uniforms.

Variants

Original = 0

The original input of the filter chain.

Source = 1

The input from the previous shader pass, or the input on the first shader pass.

OriginalHistory = 2

The input frames from previous frames.

PassOutput = 3

The output from previous shader passes in the same frame.

PassFeedback = 4

The output from previous shader passes in the previous frame.

User = 5

A user provided lookup texture.

Implementations

impl TextureSemantics

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

Get the name of the size uniform for this semantics when bound.

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

Get the name of the texture sampler for this semantics when bound.

pub fn is_indexed(&self) -> bool

Returns whether or not textures of this semantics are indexed or unique.

Only Original and Source are unique, all other textures can be indexed.

pub const fn semantics(self, index: usize) -> Semantic<TextureSemantics>

Produce a Semantic for this TextureSemantics of the given index.

Trait Implementations

impl Clone for TextureSemantics

fn clone(&self) -> TextureSemantics

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextureSemantics

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

Formats the value using the given formatter.

impl Hash for TextureSemantics

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 TextureSemantics

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

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

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