Enum RefreshError 

#[non_exhaustive]
pub enum RefreshError {
    Unknown,
    Expired,
    Replay,
    ChainRevoked,
    Unbound,
    Store(StoreError),
}

Errors raised by refresh-token rotation (cheers-server’s RefreshRotator).

Keyless, so it lives in the shared contract crate. #[non_exhaustive] so future variants don’t break callers.

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.

Unknown

The presented token isn’t in the store.

Expired

expires_at <= now for this token.

Replay

The presented token has already been rotated. The chain is now revoked as a side effect — every record sharing the chain id has revoked = true after this error returns.

ChainRevoked

The chain was previously revoked (logout, device revoke, prior replay).

Unbound

The token is live, but the caller’s binding resolver knows no DeviceBinding for its (user, device) — so there is no honest binding to mint the successor access token with. Raised before the token is consumed: the chain is left exactly as it was (R730).

Store(StoreError)

Underlying RefreshStore failure.

Trait Implementations

impl Debug for RefreshError

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

Formats the value using the given formatter.

impl Display for RefreshError

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

Formats the value using the given formatter.

impl Error for RefreshError

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<RefreshError> for Error

fn from(source: RefreshError) -> Self

Converts to this type from the input type.

impl From<StoreError> for RefreshError

fn from(source: StoreError) -> Self

Converts to this type from the input type.
