Struct AppendEntriesRequest 

pub struct AppendEntriesRequest {
    pub term: u64,
    pub leader_id: u64,
    pub prev_log_index: u64,

}

AppendEntries RPC (Raft paper Figure 2).

Invoked by leader to replicate log entries; also used as heartbeat (entries is empty).

Fields

term: u64

Leader’s term.

leader_id: u64

Leader’s ID so followers can redirect clients.

prev_log_index: u64

Index of log entry immediately preceding new ones.

prev_log_term: u64

Term of prev_log_index entry.

entries: Vec<LogEntry>

Log entries to store (empty for heartbeat).

leader_commit: u64

Leader’s commit_index.

group_id: u64

Raft group ID for Multi-Raft routing.

Trait Implementations

impl Archive for AppendEntriesRequest

where u64: Archive, Vec<LogEntry>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedAppendEntriesRequest

The archived representation of this type.

type Resolver = AppendEntriesRequestResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for AppendEntriesRequest

fn clone(&self) -> AppendEntriesRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppendEntriesRequest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AppendEntriesRequest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<AppendEntriesRequest, __D> for Archived<AppendEntriesRequest>

where u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, Vec<LogEntry>: Archive, <Vec<LogEntry> as Archive>::Archived: Deserialize<Vec<LogEntry>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<AppendEntriesRequest, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for AppendEntriesRequest

fn read<R: Read<'__msgpack_de>>(reader: &mut R) -> Result<Self, Error>

where Self: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl<__S: Fallible + ?Sized> Serialize<__S> for AppendEntriesRequest

where u64: Serialize<__S>, Vec<LogEntry>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for AppendEntriesRequest

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for AppendEntriesRequest

fn write<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Writes the MessagePack representation of this value into the provided writer.
