Enum MobStoreError 

pub enum MobStoreError {
    WriteFailed(String),
    ReadFailed(String),
    NotFound(String),
    CasConflict(String),
    SpecRevisionConflict {
        mob_id: MobId,
        expected: Option<u64>,
        actual: u64,
    },
    Serialization(String),
    Internal(String),
}

Errors from mob storage operations.

Scoped to storage concerns only — callers convert to MobError at the boundary via the From impl.

Variants

WriteFailed(String)

A write operation failed.

ReadFailed(String)

A read operation failed.

NotFound(String)

The requested entity was not found.

CasConflict(String)

A compare-and-swap precondition was not met.

SpecRevisionConflict

Spec revision compare-and-swap failed (structured variant for typed conversion).

Fields

mob_id: MobId

expected: Option<u64>

actual: u64

Serialization(String)

Serialization or deserialization failed.

Internal(String)

Internal error.

Trait Implementations

impl Debug for MobStoreError

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

Formats the value using the given formatter.

impl Display for MobStoreError

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

Formats the value using the given formatter.

impl Error for MobStoreError

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<MobStoreError> for MobError

fn from(error: MobStoreError) -> Self

Converts to this type from the input type.
