| // An interface for resolving a URI to a component. |
| // |
| // This interface is implemented by components that provide support |
| // for loading components with a particular URI scheme. For example, |
| // the Fuchsia package component resolver exposes a service with this |
| // interface to resolve component URIs using the "fuchsia-pkg://" scheme. |
| // |
| // To use a resolver to resolve URIs within your realm, register it |
| // in your realm's manifest. (TODO: explain in more detail) |
| // |
| // Note: The component manager is the only intended direct client of this |
| // interface. |

| interface ComponentResolver { |
| // Resolves a component with the given URI. |

| // |component_uri| is the unescaped URI of the component to resolve. |
| // |
| // If successful, returns |ZX_OK| and information about the component |
| // that was resolved. |
| // |
| // On failure, returns null |info| and... |
| // - |ZX_ERR_INVALID_ARGS|: The component's URI was malformed. |
| // - |ZX_ERR_NOT_FOUND|: The component does not exist. |
| // - |ZX_ERR_UNAVAILABLE|: The resolver was unable to retrieve or parse |
| // the component's resources. |
