Enum DropReason 

#[non_exhaustive]
pub enum DropReason {
    SampleTooLarge,
    FragmentSizeInvalid,
    FragmentIndexZero,
    FragmentIndexOutOfRange,
    PayloadSizeMismatch,
    InconsistentWithBuffered,
    FragmentsInSubmessageInvalid,
    PendingSnsCapExceeded,
    AssemblerDisabled,
}

Zurueckgewiesenes-Fragment-Kategorie — nur fuer Diagnostik.

Neue Varianten ergaenzen: pflegeaendernd auch die DropReason::as_str-Methode anpassen (exhaustive match), sonst bricht der Build. Das ist Absicht — so wird verhindert, dass neue Failure-Modes still in Logging-/Metrics-Pfaden verloren gehen.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SampleTooLarge

sample_size ueber Cap.

FragmentSizeInvalid

fragment_size ueber Cap oder == 0.

FragmentIndexZero

fragment_starting_num == 0 (1-basiert erwartet).

FragmentIndexOutOfRange

Fragment-Index jenseits von total_fragments.

PayloadSizeMismatch

Payload-Laenge passt nicht zu Fragment-Position.

InconsistentWithBuffered

Spaeterer DataFrag widerspricht einem schon gespeicherten (anderes sample_size oder fragment_size).

FragmentsInSubmessageInvalid

fragments_in_submessage == 0 oder inkonsistent.

PendingSnsCapExceeded

Anzahl gleichzeitig verwalteter SNs wuerde max_pending_sns uebersteigen — aelteste unvollstaendige SN wurde verworfen.

AssemblerDisabled

max_pending_sns == 0 — Assembler akzeptiert keine Eintraege.

Implementations

impl DropReason

pub const fn as_str(self) -> &'static str

Stabile String-Repraesentation fuer Logging/Metrics. Exhaustives Match — neue Varianten brechen hier absichtlich den Build.

Trait Implementations

impl Clone for DropReason

fn clone(&self) -> DropReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DropReason

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

Formats the value using the given formatter.

impl Display for DropReason

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

Formats the value using the given formatter.

impl PartialEq for DropReason

fn eq(&self, other: &DropReason) -> 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 Copy for DropReason

impl Eq for DropReason

impl StructuralPartialEq for DropReason
