Struct SyncHandshake 

pub struct SyncHandshake {
    pub version: u32,
    pub root_hash: [u8; 32],
    pub entity_count: u64,
    pub max_depth: u32,
    pub dag_heads: Vec<[u8; 32]>,
    pub has_state: bool,
    pub supported_protocols: Vec<SyncProtocolKind>,
}

Sync handshake message (Initiator → Responder).

Contains the initiator’s state summary for protocol negotiation.

See CIP §2.1 - Handshake Message.

Fields

version: u32

Protocol version for compatibility checking.

root_hash: [u8; 32]

Current Merkle root hash.

entity_count: u64

Number of entities in the tree.

max_depth: u32

Maximum depth of the Merkle tree.

dag_heads: Vec<[u8; 32]>

Current DAG heads (latest delta IDs).

has_state: bool

Whether this node has any state.

supported_protocols: Vec<SyncProtocolKind>

Supported protocols (ordered by preference).

Implementations

impl SyncHandshake

pub fn new( root_hash: [u8; 32], entity_count: u64, max_depth: u32, dag_heads: Vec<[u8; 32]>, ) -> Self

Create a new handshake message from local state.

pub fn is_version_compatible(&self, other: &Self) -> bool

Check if the remote handshake has a compatible protocol version.

pub fn is_in_sync(&self, other: &Self) -> bool

Check if root hashes match (already in sync).

Trait Implementations

impl BorshDeserialize for SyncHandshake

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 SyncHandshake

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

impl Clone for SyncHandshake

fn clone(&self) -> SyncHandshake

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyncHandshake

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

Formats the value using the given formatter.

impl Default for SyncHandshake

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SyncHandshake

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