Enum RedeemError 

pub enum RedeemError {
    InvalidInput {
        reason: RedemptionFailReason,
        public: PublicRedemptionError,
    },
    RateLimited {
        public: PublicRedemptionError,
    },
    NotRedeemable {
        reason: RedemptionFailReason,
        public: PublicRedemptionError,
    },
    ClaimLost {
        public: PublicRedemptionError,
    },
    Internal {
        cause: String,
        public: PublicRedemptionError,
    },
}

Why a code redemption flow failed (RFC-013 §10.3, RFC-012).

Carries the internal reason alongside the public-safe error so callers can log the internal cause without showing it to users.

Variants

InvalidInput

Input validation or normalization failed before any store access.

Fields

reason: RedemptionFailReason

Internal reason (log, do not display).

public: PublicRedemptionError

Public-safe mapping.

RateLimited

Rate-limit threshold exceeded before lookup.

Fields

public: PublicRedemptionError

Public-safe mapping.

NotRedeemable

No redeemable record found, or the record was expired/used/revoked.

Fields

reason: RedemptionFailReason

Internal reason (log, do not display).

public: PublicRedemptionError

Public-safe mapping (always InvalidOrExpired).

ClaimLost

The atomic claim was lost to a concurrent caller.

Fields

public: PublicRedemptionError

Public-safe mapping.

Internal

A transient store or key failure prevented the operation.

Fields

cause: String

Internal diagnostic (log, do not display).

public: PublicRedemptionError

Public-safe mapping.

Implementations

impl RedeemError

pub fn public(&self) -> &PublicRedemptionError

The public-safe error to return to callers / map to HTTP responses.

Trait Implementations

impl Debug for RedeemError

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

Formats the value using the given formatter.

impl Display for RedeemError

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

Formats the value using the given formatter.

impl Error for RedeemError

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.
