Struct BinaryData 

pub struct BinaryData(/* private fields */);

Binary Data is represented by a Two Byte Integer length which indicates the number of data bytes, followed by that number of bytes.

Thus, the length of Binary Data is limited to the range of 0 to 65,535 Bytes.

Implementations

impl BinaryData

pub const fn new() -> Self

Create an empty binary data.

pub fn from_slice(data: &[u8]) -> Result<Self, EncodeError>

Convert byte slice into binary data.

Errors

Returns error if byte slice is too large.

pub fn bytes(&self) -> usize

Get byte length used in packet.

pub fn clear(&mut self)

Clear binary data.

Trait Implementations

impl AsMut<Vec<u8>> for BinaryData

fn as_mut(&mut self) -> &mut Vec<u8>

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u8]> for BinaryData

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for BinaryData

fn clone(&self) -> BinaryData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BinaryData

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

Formats the value using the given formatter.

impl DecodePacket for BinaryData

fn decode(ba: &mut ByteArray<'_>) -> Result<Self, DecodeError>

Decode byte array into a mqtt packet.

impl Default for BinaryData

fn default() -> BinaryData

Returns the “default value” for a type.

impl EncodePacket for BinaryData

fn encode(&self, buf: &mut Vec<u8>) -> Result<usize, EncodeError>

Encode packets into byte array.

impl PartialEq for BinaryData

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