Enum SnapshotError 

pub enum SnapshotError {
    SnapshotNotFound(SnapshotId),
    PageNotFound(PageId),
    MaxSnapshotsExceeded,
    MaxPagesExceeded,
    ChecksumMismatch {
        page_id: PageId,
        expected: u64,
        got: u64,
    },
    ParentSnapshotNotFound(SnapshotId),
}

Errors returned by StorageSnapshotManager operations.

Variants

SnapshotNotFound(SnapshotId)

No snapshot with the given id was found.

PageNotFound(PageId)

No page with the given id exists in the current state.

MaxSnapshotsExceeded

The snapshot limit configured in SnapshotConfig::max_snapshots would be exceeded.

MaxPagesExceeded

The page limit configured in SnapshotConfig::max_pages would be exceeded.

ChecksumMismatch

A page’s stored checksum does not match its data.

Fields

page_id: PageId

The page whose checksum is wrong.

expected: u64

Expected (stored) checksum.

got: u64

Computed checksum over actual data.

ParentSnapshotNotFound(SnapshotId)

The snapshot specified as parent does not exist.

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.
