Struct CacheEntry 

pub struct CacheEntry {
    pub cid: String,
    pub data: Vec<u8>,
    pub inserted_at: u64,
    pub last_accessed: u64,
    pub access_count: u64,
    pub ttl_us: Option<u64>,
    pub size_bytes: usize,
    pub tags: Vec<String>,
}

A single entry stored in the cache.

Fields

cid: String

Content-derived identifier.

data: Vec<u8>

Raw payload.

inserted_at: u64

Microsecond timestamp at insertion time.

last_accessed: u64

Microsecond timestamp of most-recent access.

access_count: u64

Total number of times this entry has been retrieved.

ttl_us: Option<u64>

Optional TTL in microseconds (measured from inserted_at).

size_bytes: usize

Payload size in bytes (mirrors data.len()).

tags: Vec<String>

Arbitrary string tags for group-based operations.

Implementations

impl CacheEntry

pub fn is_expired(&self, now: u64) -> bool

Return true when the entry has passed its TTL deadline.

pub fn remaining_ttl_us(&self, now: u64) -> u64

Remaining TTL in microseconds, or u64::MAX for entries without TTL.

Trait Implementations

impl Clone for CacheEntry

fn clone(&self) -> CacheEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheEntry

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

Formats the value using the given formatter.

impl Eq for CacheEntry

impl PartialEq for CacheEntry

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