Variants

Io(Error)

Json(Error)

BrokenChain

previous_record_digest on a record didn’t match the prior record’s record_digest. The chain is broken.

Fields

index: u64

expected: String

actual: String

RecordTampered

A record’s stored record_digest didn’t match the recomputed digest. The record was tampered after write.

Fields

index: u64

expected: String

actual: String

MissingRecord

A record file referenced by the head no longer exists.

Fields

index: u64

LockBusy

The journal’s append lock could not be acquired.

MaxUsesExceeded

The append exceeds max_uses recorded on prior uses for this grant. Surfaced as an error so callers (PR 3) refuse to sign the action; PR 2 itself only writes uses passed in by callers, so this only fires from append_use when the caller didn’t preflight via check_replay.

Fields

grant_id: String

max_uses: u32

current: u32

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, f: &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 From<Error> for JournalError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for JournalError

fn from(e: Error) -> Self
