Struct tracing_log::TraceLogger

pub struct TraceLogger { /* fields omitted */ }

👎 Deprecated since 0.1.1:

A tracing Subscriber implementation that logs all recorded trace events.

Note: This API has been deprecated since version 0.1.1. In order to emit tracing events as log records, the “log” and “log-always” feature flags on the tracing crate should be used instead.
