Enum ErrorClass 

#[non_exhaustive]
pub enum ErrorClass {
    Client,
    Server,
}

Coarse responsibility class for an Error. Two values by design — “transient” / “permanent” is a retry-policy axis, orthogonal to responsibility, and surfaced via Error::Provider’s retry_after field plus the RetryClassifier policy surface.

Maps onto the standard HTTP family split: Client ≈ 4xx-equivalent (caller / integrator can act to fix), Server ≈ 5xx-equivalent (vendor or deployment must act).

JSON serialisation produces "client" / "server" to match the std::fmt::Display form — wire dashboards keying off the lower- case bucket stay consistent across the OTel / SSE / audit surfaces.

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.

Client

The caller — request shape, credentials, quota, cancellation choice — is the actor that can resolve the failure.

Server

The SDK, vendor, or deployment environment is the actor that can resolve the failure.

Trait Implementations

impl Clone for ErrorClass

fn clone(&self) -> ErrorClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorClass

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

Formats the value using the given formatter.

impl Display for ErrorClass

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

Formats the value using the given formatter.

impl Hash for ErrorClass

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ErrorClass

fn eq(&self, other: &ErrorClass) -> 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.

impl Serialize for ErrorClass

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
