Enum Error 

#[non_exhaustive]
pub enum Error {
    Codec(CodecError),
    Store(StoreError),
    Refresh(RefreshError),
    Revoked,
    PeerKeyMismatch,
    InvalidInput(String),
}

Top-level cheers error. #[non_exhaustive] so new variants are non-breaking.

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.

Codec(CodecError)

Failure inside the Codec layer.

Store(StoreError)

Failure inside a UserStore/CredentialStore/RefreshStore impl.

Refresh(RefreshError)

Failure inside refresh-token rotation — surfaced by cheers-server’s SessionAuthority::rotate.

Revoked

A token verified cryptographically but its jti is in the revocation set — surfaced by cheers-verify’s EdgeVerifier.

PeerKeyMismatch

A token verified cryptographically but is not bound to the peer public key the caller presented — either it carries no peer_key at all, or it names a different one. Surfaced by cheers-verify’s EdgeVerifier::verify_bound_at (R515): the token holder is not the connecting peer.

InvalidInput(String)

Caller passed invalid input that no specific subsystem owns (e.g. an empty subject string, a timestamp outside i64 range).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<CodecError> for Error

fn from(source: CodecError) -> Self

Converts to this type from the input type.

impl From<RefreshError> for Error

fn from(source: RefreshError) -> Self

Converts to this type from the input type.

impl From<StoreError> for Error

fn from(source: StoreError) -> Self

Converts to this type from the input type.
