Enum UpstreamErrorClass 

pub enum UpstreamErrorClass {
    AuthError,
    BadInput,
    Quota,
    RateLimited,
    ServerError,
    TransportError,
}

Coarse classification of an upstream failure. Each class maps to a distinct Sentry bucket via a unique literal tracing::error! / tracing::warn! message — that’s how grouping survives across providers without collapsing every error into one mega-bucket.

Variants

AuthError

401 / 403 / 407 — credentials missing, revoked, or insufficient.

BadInput

400 / 404 (non-no-records) / 422 — request shape was wrong.

Quota

402 — out of credit; not actionable code-side. Always Warning.

RateLimited

429 — rate limited. Often actionable as a retry; Warning level.

ServerError

5xx — upstream service broke.

TransportError

0 — no HTTP status (DNS, TCP, TLS, MCP transport error, etc.).

Implementations

impl UpstreamErrorClass

pub fn classify(upstream_status: u16) -> Self

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

Short, stable label used in Sentry tags + event extras.

pub fn is_quota_class(self) -> bool

True for classes that should NOT page on-call. The Sentry before_send hook drops these silently to keep the issue list useful — they still appear as breadcrumbs inside the next real event so context isn’t lost.

Trait Implementations

impl Clone for UpstreamErrorClass

fn clone(&self) -> UpstreamErrorClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UpstreamErrorClass

impl Debug for UpstreamErrorClass

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

Formats the value using the given formatter.

impl Eq for UpstreamErrorClass

impl PartialEq for UpstreamErrorClass

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
