Enum fidl_fuchsia_memory_attribution::ProviderRequest

pub enum ProviderRequest {
    Get {
        responder: ProviderGetResponder,
    },
    _UnknownMethod {
        ordinal: u64,
        control_handle: ProviderControlHandle,
        method_type: MethodType,
    },
}

Provides memory attribution information under this principal.

The typical expected usage of this protocol is:

• Component Runners implement this protocol and declare it in their manifest.
• A Component that wants to provide extra internal information may also declare and implement this protocol;
• Clients connect to a Provider, and use the Get methods to recursively explore the Principal hierarchy.

Clients will typically maintain the connection and start a hanging get to retrieve attribution information. Runners need to inspect the manifest of their runnees to determine if they serve this protocol, and proactively create the connection. They can also proxy this protocol in case their runnee provides attribution information in an unsuitable format.

Variants

Get

Returns the attribution information known to the provider.

The first call returns immediately with the current information. Subsequent calls will be held if no additional information is available, and return only when there are changes to the attribution information to be reported.

Runners will typically report the kernel resources (e.g. job, process, etc) associated with each component that they are responsible for running.

Components may optionally report resource usage by different categories within their implementation.

Fields

responder: ProviderGetResponder

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: ProviderControlHandle

method_type: MethodType
