Struct tracing_fluentd::FlattenFmt

pub struct FlattenFmt;

Policy to insert span data as flattent object.

Specifically, any span’s or event metadata’s attributes are inserted at the root of event record. For example, having span lolka with attribute arg: 1 would result in arg: 1 to be inserted alongside message and other attributes of the event.
