Struct TelemetrySettings 

pub struct TelemetrySettings {
    pub enabled: bool,
    pub endpoint: Option<String>,
    pub service_name: String,
    pub sample_ratio: f64,
}

What the configuration says about tracing.

Fields

enabled: bool

Whether to join and propagate trace context.

endpoint: Option<String>

The OTLP collector, if spans should be exported.

service_name: String

What this service calls itself.

sample_ratio: f64

What fraction of locally started traces to record.

Implementations

impl TelemetrySettings

pub fn from_config(config: &Config) -> Self

Read them from config.

pub fn middleware(&self) -> Option<Trace>

The middleware, or None when tracing is off.

pub fn exports(&self) -> bool

Whether spans should be exported, as opposed to only propagated.

Propagating without exporting is a perfectly good configuration — the trace id reaches every log line, which is most of the value — so an endpoint is what distinguishes the two.
