Struct Mutate 

pub struct Mutate {
    pub adds: Vec<Subscription>,
    pub removes: Vec<Vec<u8>>,
    pub history_only: bool,
    pub mutate_id: u64,
}

Add and/or remove subscriptions in place (applied atomically per frame). Topics use the kind-prefixed binary representation shared with the decentralized backend (XIP-49 §3.3.2): the first byte is the topic kind, the remainder is the identifier. This RPC initially serves TOPIC_KIND_GROUP_MESSAGES_V1 (0x00, identifier = group_id) and TOPIC_KIND_WELCOME_MESSAGES_V1 (0x01, identifier = installation_key); a topic whose kind the node does not serve fails the stream with INVALID_ARGUMENT. Future kinds (key packages, identity updates) are adopted via the capabilities advertised on Started.

Fields

adds: Vec<Subscription>

begin delivering these topics

removes: Vec<Vec<u8>>

topics to stop delivering

history_only: bool

Catch this Mutate’s adds up to the live edge — history, TopicsLive markers, and the wave’s CatchupComplete — but do NOT register them for live delivery. The markers then mean “you have everything as of now”. Combined with half-closing the request stream, this is the bounded catch-up (“sync”) mode: the server finishes the wave and then closes the stream itself. Removals in the Mutate are unaffected.

mutate_id: u64

Client-chosen correlation id, echoed on this wave’s CatchupComplete so completions are attributable when waves overlap. SHOULD be unique per stream; 0 = no correlation requested (still echoed as 0).

Trait Implementations

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mutate

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

Formats the value using the given formatter.

impl Default for Mutate

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Mutate

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for Mutate

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 Name for Mutate

const NAME: &'static str = "Mutate"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "xmtp.mls.api.v1"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for Mutate

fn eq(&self, other: &Mutate) -> 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 Mutate

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
