Enum CacheError 

#[non_exhaustive]
pub enum CacheError {
    CapacityExceeded,
    DuplicateSequenceNumber,
    ZeroDepth,
}

Fehler-Varianten fuer Cache-Operationen.

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.

CapacityExceeded

KeepAll-Cache hat seine Kapazitaet erreicht.

DuplicateSequenceNumber

Dieselbe SN wurde bereits eingefuegt.

ZeroDepth

KeepLast mit depth == 0 — jedes Insert waere sofortiges Drop. Der Fall wird bei insert abgelehnt statt silent akzeptiert.

Trait Implementations

impl Clone for CacheError

fn clone(&self) -> CacheError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheError

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

Formats the value using the given formatter.

impl PartialEq for CacheError

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