Implementations

impl ProtocolLevel

pub const fn bytes() -> usize

Get byte length in packet.

Trait Implementations

impl Clone for ProtocolLevel

fn clone(&self) -> ProtocolLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProtocolLevel

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

Formats the value using the given formatter.

impl DecodePacket for ProtocolLevel

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

Only parse protocol level in byte array.

impl Default for ProtocolLevel

fn default() -> ProtocolLevel

Returns the “default value” for a type.

impl EncodePacket for ProtocolLevel

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

Encode packets into byte array.

impl Hash for ProtocolLevel

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

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 Ord for ProtocolLevel

fn cmp(&self, other: &ProtocolLevel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ProtocolLevel

fn eq(&self, other: &ProtocolLevel) -> 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 PartialOrd for ProtocolLevel

fn partial_cmp(&self, other: &ProtocolLevel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<u8> for ProtocolLevel

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(v: u8) -> Result<Self, Self::Error>

Performs the conversion.
