Trait IntoPacketId 

pub trait IntoPacketId<T> {
    // Required method
    fn into_packet_id(self) -> Option<T>;
}

Trait for types that can be converted into an optional packet ID

This trait enables the packet_id() builder method to accept both direct values (e.g., packet_id(42)) and optional values (e.g., packet_id(Some(42)) or packet_id(None)).

Examples

use mqtt_protocol_core::mqtt::packet::IntoPacketId;

// Direct value
let id1: Option<u16> = 42u16.into_packet_id();
assert_eq!(id1, Some(42));

// Optional value
let id2: Option<u16> = Some(42u16).into_packet_id();
assert_eq!(id2, Some(42));

// None value
let id3: Option<u16> = None::<u16>.into_packet_id();
assert_eq!(id3, None);

Required Methods

fn into_packet_id(self) -> Option<T>

Convert self into an optional packet ID

Implementations on Foreign Types

impl IntoPacketId<u16> for u16

Implementation for direct u16 packet ID values

Allows direct u16 values like 42u16 to be converted to Some(42)

fn into_packet_id(self) -> Option<u16>

impl IntoPacketId<u32> for Option<u32>

Implementation for optional u32 packet ID values

Allows optional values like Some(42u32) or None::<u32> to be passed through

fn into_packet_id(self) -> Option<u32>

impl IntoPacketId<u32> for u32
