Trait ResourceLoaderComponent 

pub trait ResourceLoaderComponent:

    // Required method
    fn load_resource(
        &self,
        source: &Source,
        ctx: &impl Context,
    ) -> SendBoxFuture<MaybeEncData, ResourceLoadingError>;

    // Provided method
    fn load_transfer_encoded_resource(
        &self,
        resource: &Resource,
        ctx: &impl Context,
    ) -> SendBoxFuture<EncData, ResourceLoadingError> { ... }
}

Trait needed to be implemented for providing the resource loading parts to aCompositeContext.

Required Methods

fn load_resource( &self, source: &Source, ctx: &impl Context, ) -> SendBoxFuture<MaybeEncData, ResourceLoadingError>

Calls to Context::load_resource will be forwarded to this method.

It is the same as Context::load_resource except that a reference to the context containing this component is passed in. To prevent infinite recursion the Context.load_resource method must not be called. Additionally the Context.load_transfer_encoded_resource must not be called if it uses Context.load_resource.

Provided Methods

fn load_transfer_encoded_resource( &self, resource: &Resource, ctx: &impl Context, ) -> SendBoxFuture<EncData, ResourceLoadingError>

Calls to Context::transfer_encode_resource will be forwarded to this method.

It is the same as Context::transfer_encode_resource except that a reference to the context containing this component is passed in to make the offload and load_resource methods of Context available.

To prevent infinite recursion the load_transfer_encoded_resource method of the context must not be called.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
