Trait RenderAsset 

pub trait RenderAsset:
    Send
    + Sync
    + 'static
    + Sized {
    type SourceAsset: Asset + Clone;
    type Params: SystemParam;

    // Required method
    fn prepare(
        asset: Self::SourceAsset,
        params: &mut SystemParamItem<'_, '_, Self::Params>,
    ) -> Result<Self, PrepareAssetError<Self::SourceAsset>>;

    // Provided method
    fn label(&self) -> &str { ... }
}

Trait that describes a GPU asset extracted from a CPU asset that implements the [bevy::prelude::Asset] trait. The GPU asset is prepared from the CPU asset using the render-world system params, and can fail with a retry or fatal error.

Required Associated Types

type SourceAsset: Asset + Clone

type Params: SystemParam

Required Methods

fn prepare( asset: Self::SourceAsset, params: &mut SystemParamItem<'_, '_, Self::Params>, ) -> Result<Self, PrepareAssetError<Self::SourceAsset>>

Prepare the GPU asset from the CPU source [bevy::prelude::Asset] using the render-world system params.

Provided Methods

fn label(&self) -> &str

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
