Struct AuthenticationMethod 

pub struct AuthenticationMethod { /* private fields */ }

Implementations

impl AuthenticationMethod

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 AuthenticationMethod

pub fn new<T>(s: T) -> Result<Self, MqttError>

where T: AsRef<str>,

Creates a new string property with the given value.

Parameters

• s - The string value to set

Returns

• Ok(Self) - Successfully created property
• Err(MqttError) - If the string is invalid or too long

Examples

let prop = ContentType::new("application/json").unwrap();

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

Parses a string 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

Examples

let data = &[0x00, 0x05, b'h', b'e', b'l', b'l', b'o'];
let (prop, consumed) = ContentType::parse(data).unwrap();
assert_eq!(consumed, 7);

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 = ContentType::new("text/plain").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) -> &str

Returns the string value of this property.

Returns

A reference to the string value.

Examples

let prop = ContentType::new("application/json").unwrap();
assert_eq!(prop.val(), "application/json");

pub fn size(&self) -> usize

Returns the total size of this property in bytes.

This includes the property ID (1 byte) plus the string data size.

Returns

The total size in bytes.

Examples

let prop = ContentType::new("hello").unwrap();
assert_eq!(prop.size(), 8); // 1 (ID) + 2 (length) + 5 (data)

Trait Implementations

impl Clone for AuthenticationMethod

fn clone(&self) -> AuthenticationMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AuthenticationMethod

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

Formats the value using the given formatter.

impl Display for AuthenticationMethod

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

Formats the value using the given formatter.

impl From<AuthenticationMethod> for Property

fn from(v: AuthenticationMethod) -> Self

Converts to this type from the input type.

impl PartialEq for AuthenticationMethod

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.
