Usage failures. Display/Serialize never include a token, a URL query, or any upstream body bytes.

Variants

UnsupportedProvider

No adapter for this provider.

Fields

provider: String

AccountIdUnavailable

Codex: the access token carries no chatgpt_account_id claim, so the account header cannot be paired with the bearer. Fail closed.

IdentityMismatch

Codex: the response names a different account than the token. The pairing invariant is violated; the snapshot is discarded.

InvalidEndpointOverride

A non-pinned, non-loopback endpoint override was supplied.

Unauthorized

Provider rejected the credential (401/403).

Fields

status: u16

RateLimited

429 on the usage endpoint itself. Not proof of quota exhaustion. retry_after_s is the delta-seconds Retry-After header, if sent.

Fields

retry_after_s: Option<u64>

UpstreamStatus

Any other non-2xx status. retry_after_s: the delta-seconds Retry-After header, if sent (an HTTP-date is ignored).

Fields

status: u16

retry_after_s: Option<u64>

Redirected

3xx. Redirects are never followed.

Fields

status: u16

Timeout

No answer within the timeout: no status, no Retry-After.

Transport

Transport failure; detail is a coarse class, never a URL or body.

Fields

detail: String

BodyTooLarge

Fields

cap: usize

Malformed

Body could not be parsed; detail names the shape, never values.

Fields

detail: String

Implementations

impl UsageError

pub fn kind(&self) -> &'static str

Stable machine-readable kind (same as the serde tag).

pub fn is_auth_failure(&self) -> bool

True when the failure means the credential itself was rejected.

pub fn failure(&self) -> ObservationFailure

The typed observation failure this error stands for (kind, HTTP status, Retry-After), for selection reports and logs.

pub fn into_broker_error(self) -> BrokerError

Map onto the broker error vocabulary (secret-free by construction).

Trait Implementations

impl Clone for UsageError

fn clone(&self) -> UsageError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UsageError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UsageError

fn deserialize<__D>( __deserializer: __D, ) -> Result<UsageError, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UsageError

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

Formats the value using the given formatter.

impl Eq for UsageError

impl Error for UsageError

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<&UsageError> for UsageErrorSummary

fn from(e: &UsageError) -> UsageErrorSummary

Converts to this type from the input type.

impl PartialEq for UsageError

fn eq(&self, other: &UsageError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for UsageError

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
