Enum ProviderErrorKind 

#[non_exhaustive]
pub enum ProviderErrorKind {
    Network,
    Tls,
    Dns,
    Http(u16),
}

Provider failure category — distinguishes transport-class failures (the SDK never received a complete HTTP framing) from HTTP-class failures (the vendor responded with a status). Retry classifiers use this to make typed decisions rather than pattern-matching on status: 0 sentinels (invariant #17).

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.

Network

Connect refused, read reset, peer hangup before HTTP framing completed.

Tls

TLS handshake failure, certificate validation failure, protocol mismatch.

Dns

DNS resolution failure or SSRF allowlist rejection at the resolver.

Http(u16)

Vendor responded with an HTTP status. Carries the actual numeric code so classifiers can branch on 408|425|429|5xx.

Trait Implementations

impl Clone for ProviderErrorKind

fn clone(&self) -> ProviderErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProviderErrorKind

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

Formats the value using the given formatter.

impl Display for ProviderErrorKind

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

Formats the value using the given formatter.

impl Hash for ProviderErrorKind

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 ProviderErrorKind

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