Trait Implementations

impl ByteStruct for Fragmentation

fn read_bytes(bytes: &[u8]) -> Self

Unpacks raw bytes from a slice into a new struct

fn write_bytes(&self, bytes: &mut [u8])

Packs the struct into raw bytes and write to a slice

impl ByteStructLen for Fragmentation

const BYTE_LEN: usize = 2usize

The length of the packed bytes of this type

impl CheckFillsUnalignedBits for Fragmentation

type CheckType = [(); 1]

impl Clone for Fragmentation

fn clone(&self) -> Fragmentation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fragmentation

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

Formats the value using the given formatter.

impl Default for Fragmentation

fn default() -> Fragmentation

Returns the “default value” for a type.

impl PartialEq for Fragmentation

fn eq(&self, other: &Fragmentation) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

where W: uWrite + ?Sized,

Formats the value using the given formatter

impl Copy for Fragmentation

impl Eq for Fragmentation

impl StructuralPartialEq for Fragmentation
