Function spirit_tokio::utils::resources

pub fn resources<Config, Consumer, E, R, O, C, N>(
    extract: E,
    consumer: Consumer,
    name: N
) -> impl Helper<O, C>where
    Config: ResourceConfig<O, C>,
    Consumer: ResourceConsumer<Config, O, C>,
    C: DeserializeOwned + Send + Sync + 'static,

    R: IntoIterator<Item = Config>,
    N: Name,

Binds a ResourceConfig and ResourceConsumer together to form a Helper.

This takes an extractor function returning an iterator of ResourceConfigs from the configuration. Then it binds it together with the provided ResourceConsumer and takes care of reconfiguring the resources, spawning the appropriate number of them, etc.

If the configuration always contains exactly one instance, use resource.

Oftentimes, the configuration fragments also implement IteratedCfgHelper, so it can be used with config_helper too.
