Enum TraceError 

pub enum TraceError {
    MissingEnvVar(String),
    InvalidConfig(String),
    BackendStatus {
        backend: &'static str,
        status: u16,
        body: String,
    },
    QueueOverflow {
        backend: &'static str,
        dropped: usize,
    },
    Unsupported(&'static str),
    Serde(Error),
}

Errors surfaced by cognis-trace. Exporter-side failures are logged and counted; this enum exists for builder validation and stats.

Variants

MissingEnvVar(String)

Required environment variable is unset.

InvalidConfig(String)

Configuration value is invalid (e.g. malformed URL).

BackendStatus

Backend returned a non-2xx status.

Fields

backend: &'static str

Backend name.

status: u16

HTTP status code.

body: String

Response body (truncated for log safety).

QueueOverflow

Exporter queue overflowed; events were dropped.

Fields

backend: &'static str

Backend name.

dropped: usize

Number of events dropped.

Unsupported(&'static str)

Exporter does not support a particular feature (scores, prompts, …).

Serde(Error)

JSON serialization failed.

Trait Implementations

impl Debug for TraceError

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

Formats the value using the given formatter.

impl Display for TraceError

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

Formats the value using the given formatter.

impl Error for TraceError

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for TraceError

fn from(source: Error) -> Self

Converts to this type from the input type.
