Enum StoreError 

pub enum StoreError {
    PreconditionFailed(String),
    Conflict(String),
    NotFound(String),
    NoSuchUpload(String),
    ChecksumMismatch(String),
    Auth(String),
    Other(String),
}

Variants

PreconditionFailed(String)

412 — the guarded condition failed. Route to arbitration, never to an operator runbook (A6).

Conflict(String)

409 — a concurrent conditional writer; retry-after-arbitrate.

NotFound(String)

NoSuchUpload(String)

The assembly was fenced (aborted) under us — A8’s takeover sweep produces exactly this at a deposed hub’s Complete.

ChecksumMismatch(String)

Server-side content validation failed — the store computed a different full-object checksum than local truth claims.

Auth(String)

401/403, or an S3 code that means the same thing: the request was well-formed and we are not allowed to make it.

Split out of Other because the caller’s response is different in kind. A transient 5xx or a connection reset is “the store is having a moment, keep trying”; this is “the credentials are wrong, expired, or the policy changed”, and no amount of retrying fixes it. It reached the epoch heartbeat as an ordinary renew failure, so a rotated key produced a fence and an exit whose log line talked about lease windows — pointing an operator at the bucket, at contention, at anything but the credential that had actually expired.

RequestTimeTooSkewed belongs here too: S3 answers 403, and the cause is the node’s clock rather than the key, which is diagnosable only if the error says so.

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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.
