FragmentAssembler

Struct FragmentAssembler 

Source
pub struct FragmentAssembler { /* private fields */ }
Expand description

State eines Reassemblers.

FragmentAssembler::default() liefert einen Assembler mit AssemblerCaps::default — dem einzigen Defaults-Weg.

Implementations§

Source§

impl FragmentAssembler

Source

pub fn new(caps: AssemblerCaps) -> Self

Erzeugt einen Assembler mit den gegebenen Caps.

Source

pub fn len(&self) -> usize

Anzahl aktiver SNs.

Source

pub fn is_empty(&self) -> bool

Ist der Assembler leer?

Source

pub fn drop_count(&self) -> u64

Anzahl verworfener Fragmente seit Start (oder seit reset_diagnostics).

Source

pub fn last_drop_reason(&self) -> Option<DropReason>

Der Grund des zuletzt verworfenen Fragments, falls ueberhaupt eines verworfen wurde. Fuer Debugging/Metrics — nicht fuer Control-Flow-Entscheidungen.

Source

pub fn reset_diagnostics(&mut self)

Setzt Diagnose-Zaehler auf 0 zurueck. buffers bleiben unveraendert — das ist reine Metric-Hygiene (Long-Running-Reader wollen ihre Delta-Snapshots).

Source

pub fn has_gaps(&self) -> bool

True, wenn fuer mind. eine SN Fragmente fehlen.

Source

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

Iteriert SNs, fuer die aktuell Fragment-Luecken existieren.

Source

pub fn missing_fragments(&self, sn: SequenceNumber) -> FragmentNumberSet

Fehlende Fragmente fuer eine SN. Liefert leeren Set, wenn SN unbekannt oder bereits komplett.

Source

pub fn discard(&mut self, sn: SequenceNumber) -> bool

Entfernt den Buffer fuer diese SN (z.B. bei GAP-Signal oder nach Completion). Gibt den Buffer zurueck, falls vorhanden.

Source

pub fn insert(&mut self, df: &DataFragSubmessage) -> Option<CompletedSample>

Spielt ein DATA_FRAG ein. Liefert bei Vervollstaendigung den reassemblierten Sample.

Inkonsistente oder pathologische Fragmente werden verworfen und in drop_count gezaehlt — sie koennen nicht die interne Map ueber die Caps hinaus wachsen lassen.
