Enum FxaaQuality 

pub enum FxaaQuality {
    Low,
    Medium,
    High,
}

FXAA quality preset.

Controls the number of edge exploration iterations in the FXAA shader. Higher quality means more iterations and better edge detection at the cost of additional texture samples per pixel.

Variants

Low

4 iterations — suitable for mobile and low-end GPUs.

Medium

8 iterations — good balance of quality and performance (default).

High

12 iterations — maximum edge exploration quality.

Implementations

impl FxaaQuality

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

Returns a human-readable name for the quality preset.

pub const fn all() -> &'static [FxaaQuality]

Returns all available quality presets.

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

Returns the shader define key for this quality preset.

Used by FxaaPass to select the correct shader variant.

Trait Implementations

impl Clone for FxaaQuality

fn clone(&self) -> FxaaQuality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FxaaQuality

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

Formats the value using the given formatter.

impl Default for FxaaQuality

fn default() -> FxaaQuality

Returns the “default value” for a type.

impl Hash for FxaaQuality

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 PartialEq for FxaaQuality

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