Struct MqttBytesBuf 

pub struct MqttBytesBuf(Box<[u8]>);

Owned binary data that satisfies the MQTT v5 length limit.

This is the owned counterpart to MqttBytes.

Tuple Fields

0: Box<[u8]>

Implementations

impl MqttBytesBuf

pub const fn as_mqtt_bytes(&self) -> &MqttBytes

Returns a borrowed reference to the underlying MqttBytes.

pub const fn as_slice(&self) -> &[u8]

Returns the raw byte slice.

Methods from Deref<Target = MqttBytes>

pub const EMPTY: &'static MqttBytes

pub fn as_slice(&self) -> &[u8]

Returns the raw byte slice.

pub fn len(&self) -> usize

Returns the length in bytes.

pub fn len_u16(&self) -> u16

Returns the length as a u16 for encoding.

pub fn encoded_len(&self) -> usize

Returns the number of bytes needed to encode this value.

pub fn is_empty(&self) -> bool

Returns true if the byte slice is empty.

Trait Implementations

impl AsRef<[u8]> for MqttBytesBuf

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

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

impl AsRef<MqttBytes> for MqttBytesBuf

fn as_ref(&self) -> &MqttBytes

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

impl Borrow<MqttBytes> for MqttBytesBuf

fn borrow(&self) -> &MqttBytes

Immutably borrows from an owned value.

impl Clone for MqttBytesBuf

fn clone(&self) -> MqttBytesBuf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MqttBytesBuf

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

Formats the value using the given formatter.

impl Deref for MqttBytesBuf

type Target = MqttBytes

The resulting type after dereferencing.

fn deref(&self) -> &MqttBytes

Dereferences the value.

impl Hash for MqttBytesBuf

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MqttBytesBuf

fn eq(&self, other: &MqttBytesBuf) -> 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 TryFrom<&[u8]> for MqttBytesBuf

type Error = DataError

The type returned in the event of a conversion error.

fn try_from( data: &[u8], ) -> Result<MqttBytesBuf, <MqttBytesBuf as TryFrom<&[u8]>>::Error>

Performs the conversion.

impl TryFrom<Box<[u8]>> for MqttBytesBuf

type Error = DataError

The type returned in the event of a conversion error.

fn try_from( data: Box<[u8]>, ) -> Result<MqttBytesBuf, <MqttBytesBuf as TryFrom<Box<[u8]>>>::Error>

Performs the conversion.

impl TryFrom<Vec<u8>> for MqttBytesBuf

type Error = DataError

The type returned in the event of a conversion error.

fn try_from( data: Vec<u8>, ) -> Result<MqttBytesBuf, <MqttBytesBuf as TryFrom<Vec<u8>>>::Error>

Performs the conversion.
