Struct Varying 

pub struct Varying {
    pub label: Label,
    pub system: Option<SystemValue>,
    pub value: Value,
    pub interp: Option<Interpolation>,
    pub used: bool,
    pub provenance: VaryingProvenance,
}

One interface variable: a value passed between stages (or between a stage and the pipeline), one per label. D3D packs several into one register; they are separate here, with the register and lanes kept in provenance.

Fields

label: Label

The source’s name for it, kept for system values too (SV_Target and 1).

system: Option<SystemValue>

What the pipeline itself supplies or takes here, when it is a system value.

value: Value

The type and lane count of the varying.

interp: Option<Interpolation>

How it is interpolated, where the source states it for this varying: a pixel input the program declares. None for outputs, for stages that do not interpolate, and for an input the program never declares (a source that carries interpolation in the program body leaves it out of a signature read alone).

used: bool

Whether the program reads (an input) or writes (an output) at least one lane, as the source’s signature states.

provenance: VaryingProvenance

The source’s address of the varying.

Trait Implementations

impl Clone for Varying

fn clone(&self) -> Varying

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Varying

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

Formats the value using the given formatter.

impl Eq for Varying

impl Hash for Varying

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

where __H: Hasher,

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 Varying

fn cmp(&self, other: &Varying) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Varying

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Varying

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

impl Serialize for Varying

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
