Methods

impl EventClass

Represents a class of tracepoints. Every tracepoint of the same class shares the same set of fields. You can have as many tracepoints of the same class as you like, but tracepoint names are namespaced per provider, not per-class.

    &mut self,
    field_name: S,

    instance_name: S,
    level: LogLevel
) -> &mut Self
