Struct EnvelopeMeta 

pub struct EnvelopeMeta {
    pub cursor: Option<Cursor>,
    pub server_ns: u64,
    pub message_hash: Option<MessageHash>,
    pub topic: Option<Topic>,
    pub expiry_ns: u64,
    pub is_commit_or_proposal: bool,
}

Server-assigned metadata for one stored envelope.

Fields

cursor: Option<Cursor>

server_ns: u64

Assigned by Postgres inside the insert, from the database clock. Equal values and backwards clock steps are allowed. The client uses this as the created time, never as a cursor.

message_hash: Option<MessageHash>

topic: Option<Topic>

expiry_ns: u64

Earliest deletion eligibility: server_ns plus the retention duration. Group application messages, welcomes, and key packages default to 90 days. Identity updates, commit-log entries, and group commits or proposals never expire (0). No pruning or expiry filtering before Phase 5. Disappearing messages remain a client-side feature.

is_commit_or_proposal: bool

Group messages only: the parsed content type is a commit or proposal. False for other payload kinds. This does not authenticate the sender.

Trait Implementations

impl Clone for EnvelopeMeta

fn clone(&self) -> EnvelopeMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnvelopeMeta

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

Formats the value using the given formatter.

impl Default for EnvelopeMeta

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EnvelopeMeta

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for EnvelopeMeta

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for EnvelopeMeta

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 EnvelopeMeta

const NAME: &'static str = "EnvelopeMeta"

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.backend.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 EnvelopeMeta

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.
