Struct vector::components::validation::ExternalResource

pub struct ExternalResource {
    pub direction: ResourceDirection,
    pub codec: ResourceCodec,
    /* private fields */
}
Expand description

An external resource associated with a component.

External resources represent the hypothetical location where, depending on whether the component is a source or sink, data would be generated from or collected at. This includes things like network endpoints (raw sockets, HTTP servers, etc) as well as files on disk, and more. In other words, an external resource is a data dependency associated with the component, whether the component depends on data from the external resource, or the external resource depends on data from the component.

An external resource includes a direction – push or pull – as well as the fundamental definition of the resource, such as HTTP or file. The component type is used to further refine the direction of the resource, such that a “pull” resource used with a source implies the source will pull data from the external resource, whereas a “pull” resource used with a sink implies the external resource must pull the data from the sink.
