Struct ComponentSnapshotProto 

pub struct ComponentSnapshotProto {
    pub type_name: String,
    pub instance_id: u32,
    pub payload: Vec<u8>,
}

Snapshot of a single Component’s state, opaque to the framework.

Fields

type_name: String

ConcreteComponent::TYPE_NAME of the component. The framework routes the payload to the matching captured restore_fn during Node::restore by (type_name, instance_id) lookup.

instance_id: u32

Per-Node instance disambiguator. Matches the instance_id assigned at Module::build() recording time (Graph::register_concrete::<T>(&T)).

payload: Vec<u8>

The component’s serialized state bytes — exactly what ConcreteComponent::serialize(&self) -> Vec<u8> returned. Restored via ConcreteComponent::restore(bytes) -> Result<Self, RestoreError>.

Trait Implementations

impl Clone for ComponentSnapshotProto

fn clone(&self) -> ComponentSnapshotProto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentSnapshotProto

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

Formats the value using the given formatter.

impl Default for ComponentSnapshotProto

fn default() -> ComponentSnapshotProto

Returns the “default value” for a type.

impl Message for ComponentSnapshotProto

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ComponentSnapshotProto

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