Struct VShardEnvelope 

pub struct VShardEnvelope {
    pub version: u16,
    pub msg_type: VShardMessageType,
    pub source_node: u64,
    pub target_node: u64,
    pub vshard_id: u32,
    pub payload: Vec<u8>,
}

Envelope wrapping all vShard wire messages.

Fields

version: u16

Protocol version for forward compatibility.

msg_type: VShardMessageType

Message type discriminant.

source_node: u64

Source node ID.

target_node: u64

Target node ID.

vshard_id: u32

vShard being referenced.

payload: Vec<u8>

Opaque payload (type-dependent).

Implementations

impl VShardEnvelope

pub fn new( msg_type: VShardMessageType, source_node: u64, target_node: u64, vshard_id: u32, payload: Vec<u8>, ) -> Self

pub fn to_bytes(&self) -> Vec<u8>

Serialize to bytes (transport-agnostic).

Binary format (v2, all little-endian): version(2) + msg_type(2) + source(8) + target(8) + vshard(4) + payload_len(4) + payload

pub fn from_bytes(buf: &[u8]) -> Option<Self>

Deserialize from bytes.

Trait Implementations

impl Clone for VShardEnvelope

fn clone(&self) -> VShardEnvelope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VShardEnvelope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VShardEnvelope

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VShardEnvelope

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

impl Serialize for VShardEnvelope

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
