Struct relm4::RelmMsgHandler

pub struct RelmMsgHandler<Data, ParentModel>where
    Data: MessageHandler<ParentModel> + 'static,
    ParentModel: Model,{ /* private fields */ }

RelmMsgHandlers are usually used to run expansive tasks on different threads and report back when they are finished so that their parent components can keep handling UI events in the meantime. For example you could use a RelmMsgHandler for sending a HTTP request or for copying files.

Multiple RelmMsgHandlers that have the same parent are usually bundled along with RelmComponents and RelmWorkers in a struct that implements Components.
