Enum LogError 

pub enum LogError {
    Io(Error),
    LogOverflow,
    TruncateBeyondEnd {
        requested: u64,
        current: u64,
    },
    IncompatibleFormat {
        reason: String,
    },
}

Errors produced by CanonicalLog.

Variants

Io(Error)

Underlying filesystem / I/O error.

LogOverflow

The log’s byte length would exceed u64::MAX. A single-workspace log is not expected to hit this — included for completeness.

TruncateBeyondEnd

Truncation target is beyond the current log length.

Fields

requested: u64

Requested truncation offset.

current: u64

Current log length.

IncompatibleFormat

The file at the supplied path is not a recognizable Mimir canonical log. Either the magic prefix doesn’t match, the declared format version isn’t supported by this build, or the file is too short to carry the 8-byte header. Surfaced before any truncation or recovery logic so misrouted-path opens cannot silently destroy data.

Fields

reason: String

Human-readable diagnostic; never include the actual bytes of any payload past the header (no PII / value leakage).

Trait Implementations

impl Debug for LogError

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

Formats the value using the given formatter.

impl Display for LogError

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

Formats the value using the given formatter.

impl Error for LogError

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<LogError> for StoreError

fn from(source: LogError) -> Self

Converts to this type from the input type.

impl PartialEq for LogError

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