    ManifestNotFound {
        id: String,
    },
    ObjectNotFound {
        checksum: String,
    },
    Integrity {
        address: String,

}

Errors a Store backend can surface.

Backends wrap their own failure types (filesystem I/O, HTTP/SDK errors, integrity mismatches) into these variants. The orchestrator matches on the variant, not the wrapped cause, so behavior stays backend-agnostic.

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.

ManifestNotFound

The requested manifest (by snapshot id) was not present in the store.

Fields

id: String

The snapshot id that was looked up.

ObjectNotFound

A content object referenced by a manifest was not present in the store.

Fields

checksum: String

The object checksum that was looked up.

Integrity

Stored bytes did not hash to the address they were filed under (object checksum or manifest snapshot id mismatch) — the blob is corrupt or tampered.

Fields

address: String

The address (object path or manifest id) being verified.

expected: String

The checksum/id the address claims.

actual: String

The checksum/id actually computed over the bytes.

Parse(ParseError)

A manifest’s text could not be parsed into a Manifest.

Io(Error)

An underlying I/O failure (filesystem, network, SDK).

Backend

A backend-specific failure that does not fit the typed variants above (e.g. an SDK error from a network store). Carries a human-readable message and an optional source.

Fields

message: String

Human-readable description of the failure.

source: Option<Box<dyn Error + Send + Sync + 'static>>

The wrapped backend error, if any.

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.

impl From<Error> for StoreError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for StoreError

fn from(source: ParseError) -> Self

Converts to this type from the input type.
