Enum ServicePrincipalError 

#[non_exhaustive]
pub enum ServicePrincipalError {
    AlreadyExists(PrincipalId),
    UnknownPrincipal(PrincipalId),
    Principal(PrincipalError),
    WrongPrincipalKind(PrincipalKind),
    NoActiveKey(PrincipalId),
    Codec(CodecError),
    Store(StoreError),
}

Typed failure modes for ServicePrincipalAuthority operations.

HTTP layer (peer ticket) maps these to status codes: AlreadyExists → 409, UnknownPrincipal → 404, WrongPrincipalKind → 500 (programmer error reaching the authority with a non-service id), NoActiveKey → 500 (data integrity — every provisioned principal MUST have at least one active key), Codec → 500, Principal/Store → bubble.

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.

AlreadyExists(PrincipalId)

A principal with the requested desired_id already exists.

UnknownPrincipal(PrincipalId)

rotate (or a JWKS lookup) named a principal cheers doesn’t know.

Principal(PrincipalError)

The id handed to provision/rotate wasn’t a service kind. Bubbles up the underlying PrincipalError.

WrongPrincipalKind(PrincipalKind)

kind on the principal id was something other than Service.

NoActiveKey(PrincipalId)

rotate ran against a principal with no Active key. Indicates a data-integrity break (every provision must seed one) — not a normal user-input failure.

Codec(CodecError)

Keypair generation failed inside the codec layer.

Store(StoreError)

Underlying store failure.

Trait Implementations

impl Debug for ServicePrincipalError

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

Formats the value using the given formatter.

impl Display for ServicePrincipalError

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

impl Error for ServicePrincipalError

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.
