Struct WillProperties

pub struct WillProperties {
    pub delay_interval: Option<Duration>,
    pub payload_format_indicator: Option<u8>,
    pub message_expiry_interval: Option<Duration>,
    pub content_type: Option<String>,
    pub response_topic: Option<String>,
    pub correlation_data: Option<Bytes>,
    pub user_properties: Vec<(String, String)>,
}

Represents the properties of a Will message in MQTT v5.

These properties provide extended functionality for the last will and testament message, including delivery timing, content format, and correlation data.

Example

use std::time::Duration;
use mqute_codec::protocol::v5::WillProperties;

let will_properties = WillProperties {
    delay_interval: Some(Duration::from_secs(10)),
    content_type: Some("json".to_string()),
    ..Default::default()
};

Fields

delay_interval: Option<Duration>

Delay before sending the Will message after connection loss

payload_format_indicator: Option<u8>

Format of the Will message payload (0=bytes, 1=UTF-8)

message_expiry_interval: Option<Duration>

Lifetime of the Will message in seconds

content_type: Option<String>

Content type descriptor (MIME type)

response_topic: Option<String>

Topic name for the response message

correlation_data: Option<Bytes>

Correlation data for the response message

user_properties: Vec<(String, String)>

User-defined key-value properties

Trait Implementations

impl Clone for WillProperties

fn clone(&self) -> WillProperties

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WillProperties

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

Formats the value using the given formatter.

impl Default for WillProperties

fn default() -> WillProperties

Returns the “default value” for a type.

impl PartialEq for WillProperties

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