Enum StoreError 

pub enum StoreError {
    Io(Error),
    HashMismatch {
        expected: Oid,
        actual: Oid,
    },
}

Things that can go wrong while inserting an object.

Reads from the store (Store::open, Store::contains, and others) return a plain io::Error. This enum is only surfaced by the insert paths because they have a non-IO failure mode (hash mismatch) that needs its own variant.

Variants

Io(Error)

Filesystem-level failure.

Surfaced by operations like tempfile creation, write, rename, permission, etc.

HashMismatch

Store::insert_verified received bytes that hashed to something other than the OID the caller asserted.

The tempfile is dropped, so no half-committed object is left behind.

Fields

expected: Oid

actual: Oid

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.
