Struct InstallSnapshotRequest 

pub struct InstallSnapshotRequest {
    pub term: u64,
    pub leader_id: u64,
    pub last_included_index: u64,
    pub last_included_term: u64,
    pub offset: u64,
    pub data: Vec<u8>,
    pub done: bool,
    pub group_id: u64,
    pub total_size: u64,
}

InstallSnapshot RPC (Raft paper Figure 13).

Used when a follower is too far behind for log-based catch-up.

Fields

term: u64

Leader’s term.

leader_id: u64

Leader ID.

last_included_index: u64

The snapshot replaces all entries up through and including this index.

last_included_term: u64

Term of last_included_index.

offset: u64

Byte offset where chunk is positioned in the snapshot file.

data: Vec<u8>

Raw bytes of the snapshot chunk.

done: bool

True if this is the last chunk.

group_id: u64

Raft group ID for Multi-Raft routing.

total_size: u64

Total snapshot size in bytes. 0 means “unknown” (legacy senders or bootstrap stubs). Receivers use this only as an advisory hint; they must not reject chunks when total_size == 0.

Trait Implementations

impl Archive for InstallSnapshotRequest

where u64: Archive, Vec<u8>: Archive, bool: 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 = ArchivedInstallSnapshotRequest

The archived representation of this type.

type Resolver = InstallSnapshotRequestResolver

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 InstallSnapshotRequest

fn clone(&self) -> InstallSnapshotRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InstallSnapshotRequest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InstallSnapshotRequest

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<InstallSnapshotRequest, __D> for Archived<InstallSnapshotRequest>

where u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, Vec<u8>: Archive, <Vec<u8> as Archive>::Archived: Deserialize<Vec<u8>, __D>, bool: Archive, <bool as Archive>::Archived: Deserialize<bool, __D>,

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

Deserializes using the given deserializer

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for InstallSnapshotRequest

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 InstallSnapshotRequest

where u64: Serialize<__S>, Vec<u8>: Serialize<__S>, bool: 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 InstallSnapshotRequest

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 InstallSnapshotRequest

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

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