Enum CacheError 

pub enum CacheError {
    CacheFull,
    NotFound,
    Expired,
    NonceConsumed,
    DuplicateEntry,
}

Error types for proof cache operations.

Variants

CacheFull

Cache is full (64 entries maximum).

NotFound

Entry not found for the given (mutation_hash, nonce).

Expired

Entry has expired (TTL exceeded).

NonceConsumed

Nonce has already been consumed (single-use violation).

DuplicateEntry

Duplicate entry (same mutation_hash + nonce already exists).

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.
