Struct ObservabilityConfig 

pub struct ObservabilityConfig {
    pub namespace: Cow<'static, str>,
    pub histogram: HistogramConfig,
}

Observability configuration.

Cheap to construct, Clone-able, and Send + Sync. The captured namespace is used as a prefix for every OTel instrument name ("{namespace}.session.packets", etc.). Default prefix is "phantom".

Fields

namespace: Cow<'static, str>

Instrument-name prefix. Default "phantom".

Populated from PHANTOM_TELEMETRY_NAMESPACE by Self::from_env.

Note: this prefixes metric instrument names only. tracing span names are compile-time string literals (phantom.handshake.*, phantom.listener.*) and are not affected by this knob.

histogram: HistogramConfig

Bucket boundaries for latency instruments (handshake.duration, path.validation.duration).

Implementations

impl ObservabilityConfig

pub fn from_env() -> Self

Construct a config from environment variables. Unset or empty variables fall back to defaults.

To disable telemetry at runtime, build without the telemetry-otel Cargo feature, or simply do not point OTEL_EXPORTER_OTLP_ENDPOINT at a reachable collector — the SDK’s bounded export queue then drops telemetry at near-zero cost.

pub fn builder() -> ObservabilityConfigBuilder

Begin a programmatic builder for ObservabilityConfig.

Trait Implementations

impl Clone for ObservabilityConfig

fn clone(&self) -> ObservabilityConfig

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ObservabilityConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for ObservabilityConfig

fn default() -> Self

Returns the “default value” for a type.
