Enum tetra::graphics::scaling::ScalingMode

#[non_exhaustive]
pub enum ScalingMode {
    Fixed,
    Stretch,
    ShowAll,
    ShowAllPixelPerfect,
    Crop,
    CropPixelPerfect,
}

Algorithms that can be used to scale the game’s screen.

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.

Fixed

The game will always be displayed at its native resolution, with no scaling applied. If the window is bigger than the native resolution, letterboxing will be applied. If the window is smaller than the native resolution, it will be cropped.

Stretch

The screen will be stretched to fill the window, without trying to preserve the original aspect ratio. Distortion/stretching/squashing may occur.

ShowAll

The entire screen will be displayed as large as possible while maintaining the original aspect ratio. Letterboxing may occur.

ShowAllPixelPerfect

Works the same as ShowAll, but will only scale by integer values.

Crop

The screen will fill the entire window, maintaining the original aspect ratio but potentially being cropped.

CropPixelPerfect

Works the same as Crop, but will only scale by integer values.

Trait Implementations

impl Clone for ScalingMode

fn clone(&self) -> ScalingMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScalingMode

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

Formats the value using the given formatter.

impl PartialEq<ScalingMode> for ScalingMode

fn eq(&self, other: &ScalingMode) -> 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.
