Struct InboxReceipt 

pub struct InboxReceipt {
    pub consumer: String,
    pub message_id: String,
    pub processed_at: SystemTime,
}

A single consumer/message processing receipt.

Identified by (consumer, message_id); committed atomically with the consumer’s other writes so a redelivery of the same message is a no-op.

Fields

consumer: String

The logical consumer (e.g. a projection or service name) — the dedupe scope.

message_id: String

The transport message’s stable id.

processed_at: SystemTime

When the receipt was created (advisory). The relational backends stamp the stored processed_at server-side, so this value is not currently persisted; it exists for in-process use and forward compatibility with retention/prune.

Implementations

impl InboxReceipt

pub fn new(consumer: impl Into<String>, message_id: impl Into<String>) -> Self

Create a receipt for (consumer, message_id), stamped now.

pub fn key(&self) -> (&str, &str)

The (consumer, message_id) dedupe key.

pub fn validate(&self) -> Result<(), RepositoryError>

Reject an empty consumer or message_id so every backend behaves identically (the relational CHECK constraints are a backstop).

Trait Implementations

impl Clone for InboxReceipt

fn clone(&self) -> InboxReceipt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InboxReceipt

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

Formats the value using the given formatter.

impl Eq for InboxReceipt

impl PartialEq for InboxReceipt

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