Enum CortexAdapterError 

pub enum CortexAdapterError {
    Redex(RedexError),
    Closed,
    FoldStopped {
        seq: u64,
    },
    FoldStoppedBeforeSeq {
        wanted: u64,
        folded_through: Option<u64>,
    },
    InvalidStartPosition(&'static str),
}

Errors produced by super::CortexAdapter operations.

Variants

Redex(RedexError)

Underlying RedEX storage error.

Closed

The adapter has been closed.

FoldStopped

The fold task has stopped (first fold error under super::FoldErrorPolicy::Stop). Holds the RedEX sequence at which the fold stopped.

Fields

seq: u64

The RedEX sequence of the event whose fold returned an error.

FoldStoppedBeforeSeq

wait_for_seq was asked to wait past a seq the fold task will never reach: the task halted (close, Stop-policy halt, retention-evicted tail lag) with the folded watermark in folded_through. Pre-fix this manifested as wait_for_seq silently returning () and the caller reading state that did not reflect the requested seq.

Fields

wanted: u64

The seq the caller was waiting for.

folded_through: Option<u64>

The highest seq the fold task processed before stopping; None if it stopped without processing anything.

InvalidStartPosition(&'static str)

open was called with a StartPosition that requires externally-rehydrated state — FromSeq(n) for n > 0 or LiveOnly. Callers using these positions must construct the adapter via super::CortexAdapter::open_from_snapshot instead so the watermark and state are properly anchored to the prior events the adapter is going to skip.

Accepting these positions in open would set initial_watermark = start_seq - 1, making wait_for_seq(k) for k <= start_seq-1 return immediately — the adapter would claim those seqs were “applied” while state had never seen them.

Trait Implementations

impl Debug for CortexAdapterError

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

Formats the value using the given formatter.

impl Display for CortexAdapterError

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

Formats the value using the given formatter.

impl Error for CortexAdapterError

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<RedexError> for CortexAdapterError

fn from(source: RedexError) -> Self

Converts to this type from the input type.
