Enum JournalError 

#[non_exhaustive]
pub enum JournalError {
    DuplicateToken,
    ChainIntegrity {
        index: usize,
    },
    SignatureInvalid {
        index: usize,
    },
    BackendIo(String),
}

Journal operation error.

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.

DuplicateToken

Same-token reuse detected — replay attack.

ChainIntegrity

Chain hash recomputation mismatch — tamper detected.

Fields

index: usize

0-based index of the first failing entry.

SignatureInvalid

Ed25519 signature verification failed.

Fields

index: usize

0-based index of the first failing entry.

BackendIo(String)

Backend I/O error — used by the WAL-backed path.

Trait Implementations

impl Debug for JournalError

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

Formats the value using the given formatter.

impl Display for JournalError

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

Formats the value using the given formatter.

impl Error for JournalError

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 PartialEq for JournalError

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