Implementations§

Source§

impl AuthenticationMethod

Source

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();
Source§

impl AuthenticationMethod

Source

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();
Source

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);
Source

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();
Source

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();
Source

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");
Source

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)
