Enum SyncProtocolKind 

pub enum SyncProtocolKind {
    None,
    DeltaSync,
    HashComparison,
    Snapshot,
    BloomFilter,
    SubtreePrefetch,
    LevelWise,
}

Protocol capability identifier for sync negotiation.

This is a discriminant-only enum used for advertising which sync protocols a node supports. Unlike SyncProtocol, this does not carry protocol-specific data, making it suitable for capability comparison with contains() and equality.

See CIP §2 - Sync Handshake Protocol.

IMPORTANT: Keep variants in sync with SyncProtocol.

Variants

None

No sync needed - root hashes already match.

DeltaSync

Delta-based sync via DAG traversal.

HashComparison

Hash-based Merkle tree comparison.

Snapshot

Full state snapshot transfer.

BloomFilter

Bloom filter-based quick diff.

SubtreePrefetch

Subtree prefetch for deep localized changes.

LevelWise

Level-wise sync for wide shallow trees.

Trait Implementations

impl BorshDeserialize for SyncProtocolKind

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 SyncProtocolKind

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

impl Clone for SyncProtocolKind

fn clone(&self) -> SyncProtocolKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyncProtocolKind

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

Formats the value using the given formatter.

impl EnumExt for SyncProtocolKind

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

Deserialises given variant of an enum from the reader.

impl From<&SyncProtocol> for SyncProtocolKind

fn from(protocol: &SyncProtocol) -> Self

Converts to this type from the input type.

impl Hash for SyncProtocolKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SyncProtocolKind

fn eq(&self, other: &SyncProtocolKind) -> 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.
