Struct win_etw_provider::EventOptions

pub struct EventOptions {
    pub level: Option<Level>,
    pub activity_id: Option<GUID>,
    pub related_activity_id: Option<GUID>,
}

Allows an application to override the parameters for an event. The first parameter of each generated event method is options: Option<&EventOptions>.

Fields

level: Option<Level>

Overrides the level of the event, if present. Each event method has a default, which can be specified using (for example) #[event(level = "warn")]. If the event declaration does not specify a level, then the level will be Level::VERBOSE.

activity_id: Option<GUID>

Specifies the activity ID of this event.

related_activity_id: Option<GUID>

Specifies a related activity ID for this event. This enables an application to indicate that two sets of events are related, by associating the activity IDs of the two sets. This is sometimes known as event correlation.
