pub fn fmt_filter<S>(env_filter: EnvFilter) -> impl Filter<S>Expand description
A fmt-layer filter that lets ordinary logs through and drops both audit
streams.
A host that installs its own fmt layer alongside AuditLayer needs
this, or every audit record is printed twice — once as a raw tracing event
with all its typed fields, once rendered. act::guest is excluded for a
second reason: guest telemetry is untrusted input and has no business in
the operator’s log at all.
