pub struct SchemaMetaAssetLoader(pub fn(ctx: &mut MetaAssetLoadCtx<'_>, ptr: SchemaRefMut<'_>, deserialzer: &mut dyn Deserializer<'_>) -> Result<()>);
Expand description

A custom asset loader implementation for a metadata asset.

This is similar in purpose to implementing AssetLoader, but instead of loading from bytes, it loads from the deserialized SchemaRefMut of a metadata asset and must be added as a schema type data.
