Source§impl AssetLoader for ImageLoader
impl AssetLoader for ImageLoader
Source§type Settings = ImageLoaderSettings
type Settings = ImageLoaderSettings
The settings type used by this
AssetLoader.Source§type Error = ImageLoaderError
type Error = ImageLoaderError
The type of error which could be encountered by this loader.
Source§async fn load<'a>(
&'a self,
reader: &'a mut Reader<'_>,
settings: &'a ImageLoaderSettings,

async fn load<'a>( &'a self, reader: &'a mut Reader<'_>, settings: &'a ImageLoaderSettings, load_context: &'a mut LoadContext<'_>, ) -> Result<Image, Self::Error>
Asynchronously loads
AssetLoader::Asset (and any other labeled assets) from the bytes provided by Reader.Source§fn extensions(&self) -> &[&str]
fn extensions(&self) -> &[&str]
Returns a list of extensions supported by this
AssetLoader, without the preceding dot.
Note that users of this AssetLoader may choose to load files with a non-matching extension.Source§impl Clone for ImageLoader

fn as_bind_group_shader_type(&self, _images: &RenderAssets<GpuImage>) -> U
Return the
T ShaderType for self. When used in AsBindGroup
derives, it is safe to assume that all images in self exist.Source§impl<T> BorrowMut<T> for Twhere

Source§fn into_any(self: Box<T>) -> Box<dyn Any>
fn into_any(self: Box<T>) -> Box<dyn Any>
Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.Source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
Convert
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.Source§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.Source§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.Source§impl<T> DowncastSync for T

&self,
meta: &[u8],
) -> Result<Box<dyn AssetMetaDyn>, DeserializeMetaError>
fn deserialize_meta( &self, meta: &[u8], ) -> Result<Box<dyn AssetMetaDyn>, DeserializeMetaError>
Deserializes metadata from the input
meta bytes into the appropriate type (erased as Box<dyn AssetMetaDyn>).Source§fn default_meta(&self) -> Box<dyn AssetMetaDyn>
fn default_meta(&self) -> Box<dyn AssetMetaDyn>
Returns the default meta value for the
AssetLoader (erased as Box<dyn AssetMetaDyn>).Source§fn type_name(&self) -> &'static str
