Enum vulkano::swapchain::PresentScaling

#[non_exhaustive]
#[repr(u32)]
pub enum PresentScaling {
    OneToOne = 1,
    AspectRatioStretch = 2,
    Stretch = 4,
}

The way a swapchain image is scaled, if it does not exactly fit the surface.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OneToOne = 1

No scaling is performed; one swapchain image pixel maps to one surface pixel.

AspectRatioStretch = 2

Both axes of the image are scaled equally, without changing the aspect ratio of the image, to the largest size in which both axes fit inside the surface.

Stretch = 4

Each axis of the image is scaled independently to fit the surface, which may change the aspect ratio of the image.

Trait Implementations

impl Clone for PresentScaling

fn clone(&self) -> PresentScaling

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PresentScaling

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

Formats the value using the given formatter.

impl From<PresentScaling> for PresentScalingFlags

fn from(val: PresentScaling) -> Self

Converts to this type from the input type.

impl From<PresentScaling> for PresentScalingFlagsEXT

fn from(val: PresentScaling) -> Self

Converts to this type from the input type.

impl FromIterator<PresentScaling> for PresentScalingFlags

fn from_iter<T>(iter: T) -> Selfwhere T: IntoIterator<Item = PresentScaling>,

Creates a value from an iterator.

impl Hash for PresentScaling

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 PartialEq for PresentScaling

fn eq(&self, other: &PresentScaling) -> 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<PresentScalingFlagsEXT> for PresentScaling

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: PresentScalingFlagsEXT) -> Result<Self, Self::Error>

Performs the conversion.
