}

Errors that can occur during snapshot sync.

Variants

SnapshotRequired

Peer’s delta history is pruned; full snapshot required.

InvalidBoundary

The requested boundary is invalid or no longer available.

ResumeCursorInvalid

Resume cursor is invalid or expired.

SnapshotOnInitializedNode

Attempted to apply snapshot on a node with existing state. INVARIANT I5: Snapshot is ONLY for fresh nodes.

RootHashMismatch

Root hash verification failed. INVARIANT I7: Verification REQUIRED before apply.

Fields

expected: [u8; 32]

computed: [u8; 32]

TransferInterrupted

Snapshot transfer was interrupted.

Fields

pages_received: usize

DecompressionFailed

Decompression failed.

EntityCountMismatch

Entity count does not match expected count.

Fields

expected: usize

actual: usize

MissingPages

Some pages are missing from the snapshot transfer.

Fields

missing: Vec<usize>

Trait Implementations

impl BorshDeserialize for SnapshotError

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for SnapshotError

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for SnapshotError

fn clone(&self) -> SnapshotError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SnapshotError

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

Formats the value using the given formatter.

impl EnumExt for SnapshotError

fn deserialize_variant<__R: Read>( reader: &mut __R, variant_tag: u8, ) -> Result<Self, Error>

Deserialises given variant of an enum from the reader.

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.
