Enum ReplayLogError 

#[non_exhaustive]
pub enum ReplayLogError {
    Io {
        op: &'static str,
        path: Arc<str>,
        source: Error,
    },
    HeaderMismatch {
        path: Arc<str>,

    },
}

Errors surfaced by the replay-log surface. Every variant carries an actionable Fix: hint.

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.

Io

I/O syscall on the log file failed.

Fields

op: &'static str

Syscall name (open, seek, read, write).

path: Arc<str>

Path the syscall was issued against.

source: Error

Underlying io::Error.

HeaderMismatch

Log header magic or version mismatch.

Fields

path: Arc<str>

Log path.

ZeroCapacity

Capacity of 0 is rejected - a zero-capacity log never accepts writes.

CapacityOverflow

Record capacity exceeds the replay-log bound. Capping here prevents malformed log headers from forcing host OOM during replay and keeps record offsets within checked arithmetic.

Fields

count: u64

Requested capacity.

max: u64

Maximum accepted capacity.

Trait Implementations

impl Debug for ReplayLogError

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

Formats the value using the given formatter.

impl Display for ReplayLogError

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

Formats the value using the given formatter.

impl Error for ReplayLogError

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<ReplayLogError> for PipelineError

Let callers bridge ReplayLogError into the unified PipelineError surface when driving the log from the megakernel pump loop.

fn from(err: ReplayLogError) -> Self

Converts to this type from the input type.
