Trait ExtractResource 

Source 
pub trait ExtractResource<L, F = ()>: Resource
where
    L: AppLabel,
{
    type Source: Resource;

    // Required method
    fn extract_resource(source: &Self::Source) -> Self;
}
Expand description

Describes how a resource gets extracted for processing.

Therefore the resource is transferred from the “main world” into the “sub world” in the ExtractSchedule step.

The marker type F is only used as a way to bypass the orphan rules. To implement the trait for a foreign type you can use a local type as the marker, e.g. the type of the plugin that calls ExtractResourcePlugin.

Required Associated Types§

type Source: Resource

Required Methods§
