Trait Implementations

impl Debug for PacketType

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

Formats the value using the given formatter.

impl Default for PacketType

fn default() -> PacketType

Returns the “default value” for a type.

impl Eq for PacketType

impl From<PacketType> for u64

fn from(value: PacketType) -> Self

Converts to this type from the input type.

impl From<u64> for PacketType

fn from(value: u64) -> Self

Converts to this type from the input type.

impl PartialEq for PacketType

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