Enum ProgressError 

pub enum ProgressError {
    Faulted,
    StaleGeneration,
    EmptyGroup,
    OpExhausted,
    BeyondAccepted,
    WriteGap,
    BeyondWritten,
}

Invalid or stale journal transition. No error advances any prefix.

Variants

Faulted

The writer has an uncertain I/O outcome and needs recovery.

StaleGeneration

Completion belongs to another writer incarnation.

EmptyGroup

A write group must contain at least one operation.

OpExhausted

Operation numbering cannot wrap.

BeyondAccepted

Completion claims operations that were never admitted.

WriteGap

An earlier complete write has not been reported.

BeyondWritten

Sync claims data not known to have been completely written.

impl Eq for ProgressError

impl Error for ProgressError

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 ProgressError

fn eq(&self, other: &Self) -> bool
