Struct ComponentContext 

pub struct ComponentContext { /* private fields */ }

A component context.

Component contexts uniquely identify a component within a topology by coupling the component identifier (name) and component type (source, transform, destination, forwarder, or encoder).

Practically speaking, all components are required to have a unique identifier. However, identifiers may be opaque enough that without knowing the type of component, the identifier doesn’t provide enough information.

Implementations

impl ComponentContext

pub fn source(component_id: ComponentId) -> Self

Creates a new ComponentContext for a source component with the given identifier.

pub fn transform(component_id: ComponentId) -> Self

Creates a new ComponentContext for a transform component with the given identifier.

pub fn destination(component_id: ComponentId) -> Self

Creates a new ComponentContext for a destination component with the given identifier.

pub fn forwarder(component_id: ComponentId) -> Self

Creates a new ComponentContext for a forwarder component with the given identifier.

pub fn encoder(component_id: ComponentId) -> Self

Creates a new ComponentContext for a encoder component with the given identifier.

pub fn component_id(&self) -> &ComponentId

Returns the component identifier.

pub fn component_type(&self) -> ComponentType

Returns the component type.
