Struct MessageReadyEvent 

pub struct MessageReadyEvent {
    pub msg_id: i64,
    pub queue_name: String,
    pub namespace: String,
    pub ready_at: DateTime<Utc>,
    pub metadata: HashMap<String, String>,
    pub visibility_timeout_seconds: Option<i32>,
}

Event emitted when a message is ready for processing

This event is triggered when a message is enqueued in PGMQ and becomes available for processing by workers. It provides the message ID and queue information needed to claim and process the message.

Examples

use tasker_pgmq::MessageReadyEvent;
use chrono::Utc;
use std::collections::HashMap;

let event = MessageReadyEvent {
    msg_id: 42,
    queue_name: "tasks_queue".to_string(),
    namespace: "tasks".to_string(),
    ready_at: Utc::now(),
    metadata: HashMap::new(),
    visibility_timeout_seconds: Some(30),
};

assert_eq!(event.msg_id, 42);
assert_eq!(event.queue_name, "tasks_queue");
assert_eq!(event.namespace, "tasks");

Fields

msg_id: i64

ID of the message that’s ready

queue_name: String

Queue where the message is available

namespace: String

Extracted namespace from the queue name

ready_at: DateTime<Utc>

When the message became ready

metadata: HashMap<String, String>

Optional message metadata (limited by payload size)

visibility_timeout_seconds: Option<i32>

Visibility timeout if applicable

Implementations

impl MessageReadyEvent

pub fn new<S: Into<String>>(msg_id: i64, queue_name: S, namespace: S) -> Self

Create a new message ready event

pub fn with_timestamp<S: Into<String>>( msg_id: i64, queue_name: S, namespace: S, ready_at: DateTime<Utc>, ) -> Self

Create with custom timestamp

pub fn with_metadata(self, metadata: HashMap<String, String>) -> Self

Add metadata to the event

pub fn add_metadata<K: Into<String>, V: Into<String>>( self, key: K, value: V, ) -> Self

Add a single metadata entry

pub fn with_visibility_timeout(self, timeout_seconds: i32) -> Self

Set visibility timeout

Trait Implementations

impl Clone for MessageReadyEvent

fn clone(&self) -> MessageReadyEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageReadyEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageReadyEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageReadyEvent

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
