Enum ObservabilityError 

#[non_exhaustive]
pub enum ObservabilityError {
    BadFilter {
        filter: String,
        source: Box<dyn StdError + Send + Sync>,
    },
    OtelInit {
        context: Option<String>,
        source: Box<dyn StdError + Send + Sync>,
    },
    OtelDisabled,
}

Error returned by the public initialisation entry points (init_logging, otel_layer::init_with_otel).

Marked #[non_exhaustive] so future variants (e.g. registry-already- installed, exporter-handshake-failed) can be added without breaking existing pattern matching.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BadFilter

The log filter directive (passed via LoggingConfig::level) could not be parsed by tracing-subscriber’s EnvFilter.

Fields

filter: String

The directive string that failed to parse.

source: Box<dyn StdError + Send + Sync>

Underlying parse error from tracing-subscriber.

OtelInit

The OTLP / OpenTelemetry exporter pipeline failed to install. Common causes: TLS setup mismatch, the global tracer provider was already installed, or the collector endpoint was unreachable on the synchronous handshake.

Fields

context: Option<String>

Optional human-friendly context (e.g. “install_batch failed”).

source: Box<dyn StdError + Send + Sync>

Underlying error from the OTel pipeline builder.

OtelDisabled

The crate was built without the otel feature but the caller asked for the OTel-aware initialiser. Rebuild with --features otel (or, when consuming via the umbrella hwhkit crate, --features otel) and try again.

Trait Implementations

impl Debug for ObservabilityError

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

Formats the value using the given formatter.

impl Display for ObservabilityError

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

Formats the value using the given formatter.

impl Error for ObservabilityError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
