Struct tracing_subscriber::registry::Data
source · [−]pub struct Data<'a> { /* private fields */ }
Expand description
Span data stored in a Registry
.
The registry stores well-known data defined by tracing: span relationships,
metadata and reference counts. Additional user-defined data provided by
Layer
s, such as formatted fields, metrics, or distributed traces should
be stored in the extensions typemap.
