Enum SurfaceColorFormat 

pub enum SurfaceColorFormat {
    Rgba8Unorm,
    Rgba8UnormSrgb,
    Bgra8Unorm,
    Bgra8UnormSrgb,
    Rgb10a2Unorm,
    Rgba16Float,
}

A supported colour surface format.

Variants

Rgba8Unorm

8 bits per channel, sRGB-encoded. Standard SDR format.

Rgba8UnormSrgb

8 bits per channel, gamma-corrected sRGB (GPU applies sRGB encoding on store / decoding on sample).

Bgra8Unorm

8 bits per channel, BGRA byte order (common on Windows/Metal).

Bgra8UnormSrgb

8 bits per channel, BGRA, sRGB.

Rgb10a2Unorm

10 bits per colour channel + 2-bit alpha, sRGB. Increases precision for SDR content; may be used for extended-range (scRGB) content.

Rgba16Float

16 bits per channel, floating-point (linear light). HDR-capable.

Implementations

impl SurfaceColorFormat

pub fn wgpu_format(self) -> TextureFormat

Return the corresponding wgpu::TextureFormat.

pub fn is_hdr(self) -> bool

Return true if this format is capable of representing HDR values (i.e. luminance > 1.0 in linear light).

pub fn bits_per_channel(self) -> u32

Return the nominal bits per channel for this format.

pub fn expects_linear_light(self) -> bool

Return true if the GPU pipeline should output linear light values when rendering into this format (as opposed to gamma-encoded sRGB).

Rgba16Float expects linear light. The Unorm variants are usually treated as gamma-encoded sRGB in practice; the UnormSrgb variants have explicit sRGB encoding built into the attachment load/store.

Trait Implementations

impl Clone for SurfaceColorFormat

fn clone(&self) -> SurfaceColorFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SurfaceColorFormat

impl Debug for SurfaceColorFormat

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

Formats the value using the given formatter.

impl Default for SurfaceColorFormat

fn default() -> SurfaceColorFormat

Returns the “default value” for a type.

impl Eq for SurfaceColorFormat

impl Hash for SurfaceColorFormat

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 SurfaceColorFormat

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