Struct tracing_tunnel::PersistedSpans

source ·
pub struct PersistedSpans { /* private fields */ }
Available on crate feature receiver only.
Expand description

Information about alive tracing spans for a particular execution that is (de)serializable and can be persisted across multiple TracingEventReceiver lifetimes.

Unlike PersistedMetadata, PersistedSpans are specific to an executable invocation (e.g., a WASM module instance). Compared to LocalSpans, PersistedSpans have the lifetime of the execution and not the host Subscriber.
