Struct SubscriptionIdentifier 

pub struct SubscriptionIdentifier { /* private fields */ }

Implementations

impl SubscriptionIdentifier

pub fn id(&self) -> PropertyId

Returns the PropertyId of this property.

Returns

The PropertyId enum value.

Examples

let prop = Property::new(...);
let id = prop.id();

impl SubscriptionIdentifier

pub fn new(v: u32) -> Result<Self, MqttError>

Creates a new variable integer property with the given value.

Parameters

• v - The u32 value to set (encoded as variable byte integer)

Returns

• Ok(Self) - Successfully created property
• Err(MqttError) - If the value fails validation or is out of range

Examples

let prop = SubscriptionIdentifier::new(42).unwrap();

pub fn parse(bytes: &[u8]) -> Result<(Self, usize), MqttError>

Parses a variable integer property from the given byte slice.

Parameters

• bytes - The byte slice to parse from

Returns

• Ok((Self, usize)) - The parsed property and number of bytes consumed
• Err(MqttError) - If parsing fails or validation fails

Examples

let data = &[0x2A]; // 42 as variable byte integer
let (prop, consumed) = SubscriptionIdentifier::parse(data).unwrap();
assert_eq!(consumed, 1);

pub fn to_buffers(&self) -> Vec<IoSlice<'_>>

Converts the property to I/O slices for efficient transmission.

Returns

A vector of I/O slices containing the property data.

Examples

let prop = SubscriptionIdentifier::new(42).unwrap();
let buffers = prop.to_buffers();

pub fn to_continuous_buffer(&self) -> Vec<u8>

Converts the property to a continuous buffer.

Returns

A byte vector containing the complete property data.

Examples

let prop = Property::new(...).unwrap();
let buffer = prop.to_continuous_buffer();

pub fn val(&self) -> u32

Returns the u32 value of this property.

Returns

The u32 value encoded as a variable byte integer.

Examples

let prop = SubscriptionIdentifier::new(42).unwrap();
assert_eq!(prop.val(), 42);

pub fn size(&self) -> usize

Returns the total size of this property in bytes.

This includes the property ID (1 byte) plus the variable byte integer size.

Returns

The total size in bytes.

Examples

let prop = SubscriptionIdentifier::new(42).unwrap();
assert_eq!(prop.size(), 2); // 1 (ID) + 1 (value < 128)

Trait Implementations

impl Clone for SubscriptionIdentifier

fn clone(&self) -> SubscriptionIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubscriptionIdentifier

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

Formats the value using the given formatter.

impl Display for SubscriptionIdentifier

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

Formats the value using the given formatter.

impl From<SubscriptionIdentifier> for Property

fn from(v: SubscriptionIdentifier) -> Self

Converts to this type from the input type.

impl PartialEq for SubscriptionIdentifier

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

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
