Struct OtelConfig 

pub struct OtelConfig {
    pub enabled: bool,
    pub service_name: Option<String>,
    pub endpoint: Option<String>,
    pub headers: HashMap<String, String>,
}

Configuration for OpenTelemetry integration.

Inert. It used to drive an OTLP exporter; that exporter is gone (see the module docs for why), and nothing reads these fields any more except the enabled flag, which setup_logging warns about so an operator who configured a collector is told to their face that nothing is being sent.

It is kept, rather than deleted with the exporter, because it lives in the types feature and four backends name it in a LoggingConfig struct literal. It carries no dependency of its own – a bool, two Option<String>s and a map – so keeping it costs nothing and removing it would be a source break with no compile-time benefit. It is also the seam to reattach an exporter to, if one ever comes back on a tokio-free transport.

Fields

enabled: bool

Whether OTel log/trace forwarding was requested. Requesting it now only warns.

service_name: Option<String>

Service name that would identify this application to a collector.

endpoint: Option<String>

OTLP collector endpoint (e.g., “http://localhost:4318”).

headers: HashMap<String, String>

Additional headers that would be sent with OTLP requests (e.g., authentication).
