Enum OauthUsageError 

pub enum OauthUsageError {
    NoCredentials,
    Expired,
    Unauthorized(u16),
    ScopeInsufficient,
    RateLimited {
        retry_after: Option<Duration>,
        snapshot: Option<Box<UsageSnapshot>>,
    },
    HttpStatus(u16, String),
    Network(String),
    UaProbe(String),
    Decode(String),
}

Failure modes for the OAuth usage fetcher.

Variants

NoCredentials

No OAuth credentials were resolved. Caller should advise the account’s own repair path.

Expired

Credentials present but expired locally; caller should surface the account’s own repair path.

Unauthorized(u16)

API returned 401/403. Token may be stale or revoked.

ScopeInsufficient

API returned 403 with oauth_scope_insufficient: the token authenticated but lacks the user:profile scope this endpoint requires. The verdict on a VALID setup token, not an auth failure - setup tokens carry user:inference only.

RateLimited

API returned 429. retry_after is the parsed Retry-After header value (in seconds) when present - Anthropic returns per-account hold-down durations that the caller should honour to avoid hammering the endpoint and keeping the limit hot. snapshot is the plan windows the response still carried: the one answer that most needs them is the one saying which window is spent.

Fields

retry_after: Option<Duration>

snapshot: Option<Box<UsageSnapshot>>

HttpStatus(u16, String)

API returned an unexpected non-success status (anything other than 200 / 401 / 403 / 429).

Network(String)

Network error reaching the API.

UaProbe(String)

The claude --version probe that supplies the User-Agent failed - a local exec problem, not a reachability verdict.

Decode(String)

Response body could not be parsed.

Implementations

impl OauthUsageError

pub fn is_rate_limited(&self) -> bool

True when this is a 429 rate-limit response. Used by callers that schedule the next probe attempt against the Retry-After value.

Trait Implementations

impl Debug for OauthUsageError

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

Formats the value using the given formatter.

impl Display for OauthUsageError

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

Formats the value using the given formatter.

impl Error for OauthUsageError

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 PartialEq for OauthUsageError

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

Equality operator ==.

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

Inequality operator !=.
