Struct FragmentNumberSet 

pub struct FragmentNumberSet {
    pub bitmap_base: FragmentNumber,
    pub num_bits: u32,
    pub bitmap: Vec<u32>,
}

Bitset von FragmentNumber-Werten ab bitmap_base. Analog zu SequenceNumberSet, aber mit FragmentNumber (u32) als Base statt SequenceNumber.

Wire-Layout: bitmapBase: 4 Byte (FragmentNumber, LE oder BE gemaess Header) numBits: 4 Byte (u32) bitmap: ceil(numBits/32) * 4 Byte

Fields

bitmap_base: FragmentNumber

Erstes Fragment, fuer das das erste Bit zustaendig ist.

num_bits: u32

Anzahl gueltiger Bits.

bitmap: Vec<u32>

ceil(num_bits/32) u32-Worte.

Implementations

impl FragmentNumberSet

pub fn wire_size(num_bits: u32) -> usize

Wire-Size in Bytes.

pub fn from_missing(base: FragmentNumber, missing: &[FragmentNumber]) -> Self

Baut das Set aus einer sortierten Liste fehlender Fragmente. base = kleinste noch nicht bestaetigte FragmentNumber.

pub fn iter_set(&self) -> impl Iterator<Item = FragmentNumber> + '_

Iteriert ueber alle gesetzten FragmentNumbers.

pub fn encoded_size(&self) -> usize

Tatsaechliche Wire-Size dieses Sets.

pub fn write_to(&self, out: &mut Vec<u8>, little_endian: bool)

Encoded das Set in out.

pub fn read_from( bytes: &[u8], offset: usize, little_endian: bool, ) -> Result<(Self, usize), WireError>

Decoded ein Set aus bytes ab offset.

Errors

UnexpectedEof.

Trait Implementations

impl Clone for FragmentNumberSet

fn clone(&self) -> FragmentNumberSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FragmentNumberSet

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

Formats the value using the given formatter.

impl PartialEq for FragmentNumberSet

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