Struct OrderingSessionSnapshot 

pub struct OrderingSessionSnapshot {
    pub session_id: Uuid,
    pub sender: Option<ActorAddr>,
    pub last_released_seq: u64,
    pub expected_next_seq: u64,
    pub buffered_count: usize,
    pub oldest_buffered_seq: Option<u64>,
    pub newest_buffered_seq: Option<u64>,
}

Per-session receiver-local ordering snapshot. This does not lock the work queue or hold sequencing state across awaits.

Fields

session_id: Uuid

Identifier of the session whose ordering state this snapshot describes; matches SeqInfo::Session { session_id, .. } on the wire.

sender: Option<ActorAddr>

Sender ActorAddr captured by the first-non-None-wins rule. None when every message in this session bypassed the normal stamping sites (rare: test fixtures, non-handler routes).

last_released_seq: u64

Highest seq released from the reorder buffer into the actor work queue. NOT “handler processed” – that’s downstream of the queue.

expected_next_seq: u64

last_released_seq + 1 – the seq the next contiguous send must carry for delivery without further buffering.

buffered_count: usize

Number of messages currently sitting in the reorder buffer waiting for a seq gap to be filled. Zero on healthy in-order sessions.

oldest_buffered_seq: Option<u64>

Lowest seq currently buffered. None when buffered_count == 0.

newest_buffered_seq: Option<u64>

Highest seq currently buffered. None when buffered_count == 0.

Trait Implementations

impl AttrValue for OrderingSessionSnapshot

fn display(&self) -> String

Display the value, typically using std::fmt::Display. This is called to show the output in human-readable form.

fn parse(value: &str) -> Result<Self, Error>

Parse a value from a string, typically using std::str::FromStr.

impl Clone for OrderingSessionSnapshot

fn clone(&self) -> OrderingSessionSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderingSessionSnapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OrderingSessionSnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for OrderingSessionSnapshot

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

Formats the value using the given formatter.

impl FromStr for OrderingSessionSnapshot

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Named for OrderingSessionSnapshot

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

A globally unique numeric identifier for this type.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.

impl PartialEq for OrderingSessionSnapshot

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
