Errors from crate::store - blockstore operations.

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.

CidMismatch

The CID attached to a put does not match a hash of the bytes. Returned only by backends that choose to verify - the default contract trusts the caller (ARCHITECTURE §3.1; see also the Phase 1 risk review: re-hashing on every put is a hot-path tax).

Fields

claimed: Cid

CID the caller asserted.

computed: Cid

CID the backend computed from the bytes.

NotFound

A CID referenced by a tree walk (lookup, cursor, diff, GC, …) is not present in the blockstore. Indicates a broken or partial tree.

Fields

cid: Cid

The CID that was looked up and missing.

Io(String)

Backend-specific I/O failure, translated into a string.

Corruption

On-disk content does not hash to the CID it is stored under. Indicates silent disk corruption or a store-level bug (e.g. a put_trusted caller that violated the safety contract). The caller MUST treat this as an unrecoverable integrity failure for the affected block.

Fields

cid: String

The CID that was requested (and used as the storage key).

detail: String

Human-readable description of the mismatch.

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<StoreError> for Error

fn from(source: StoreError) -> Self

Converts to this type from the input type.
