Enum SnapshotError 

pub enum SnapshotError {
    SnapshotNotFound(u64),
    CannotDeleteNonOldest,
    EmptySnapshotChain,
    DeltaChainBroken,
}

Errors returned by StorageSnapshotManager operations.

Variants

SnapshotNotFound(u64)

The requested snapshot id was not found.

CannotDeleteNonOldest

Attempted to delete a snapshot that is not the oldest.

EmptySnapshotChain

Operation requires at least one snapshot but none exist.

DeltaChainBroken

The delta chain is broken (an incremental snapshot references a missing predecessor).

Trait Implementations

impl Debug for SnapshotError

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

Formats the value using the given formatter.

impl Display for SnapshotError

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

Formats the value using the given formatter.

impl Eq for SnapshotError

impl Error for SnapshotError

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 PartialEq for SnapshotError

fn eq(&self, other: &SnapshotError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
