Enum Traversal 

pub enum Traversal {
    OutOfOrder {
        expected_offset: u64,
        actual_offset: u64,
        prev_error: Option<Box<Self>>,
    },
    Forked {

    },
    Checksum {

    Io(Error),
}

Error yielded by public commitlog iterators.

Variants

OutOfOrder

Fields

expected_offset: u64

actual_offset: u64

prev_error: Option<Box<Self>>

If the next segment starts with a commit with matching offset, a previous bad commit will be ignored. If, however, the offset does not match, prev_error contains the error encountered when trying to read the previous commit (which was skipped).

Forked

The log is considered forked iff a commit with the same min_tx_offset but a different crc32 than the previous commit is encountered.

This may happen in rare circumstances where a write was considered failed (e.g. due to a failed fsync(2)), when it was actually successful.

Fields

offset: u64

Decode

Fields

offset: u64

source: DecodeError

Checksum

Fields

offset: u64

Trait Implementations

impl Debug for Traversal

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

Formats the value using the given formatter.

impl Display for Traversal

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

Formats the value using the given formatter.

impl Error for Traversal

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.
