Enum webrender::internal_types::TextureSource

pub enum TextureSource {
    Invalid,
    TextureCache(CacheTextureId, Swizzle),
    External(DeferredResolveIndex, ImageBufferKind),
    Dummy,
}

Identifies the source of an input texture to a shader.

Variants

Invalid

Equivalent to None, allowing us to avoid using Options everywhere.

TextureCache(CacheTextureId, Swizzle)

An entry in the texture cache.

External(DeferredResolveIndex, ImageBufferKind)

An external image texture, mananged by the embedding.

Dummy

Select a dummy 1x1 white texture. This can be used by image shaders that want to draw a solid color.

Implementations

impl TextureSource

fn combine(&self, other: TextureSource) -> TextureSource

impl TextureSource

pub fn image_buffer_kind(&self) -> ImageBufferKind

pub fn is_compatible(&self, other: &TextureSource) -> bool

Trait Implementations

impl Clone for TextureSource

fn clone(&self) -> TextureSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextureSource

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

Formats the value using the given formatter.

impl Hash for TextureSource

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 TextureSource

fn eq(&self, other: &TextureSource) -> 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 Serialize for TextureSource

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
