Struct TtlEntry 

pub struct TtlEntry<V> {
    pub value: V,
    pub inserted_at_secs: u64,
    pub ttl_secs: u64,
}

A single cache entry with an embedded TTL deadline.

Fields

value: V

The cached value.

inserted_at_secs: u64

Epoch-seconds at which this entry was inserted.

ttl_secs: u64

Lifetime in seconds from insertion.

Implementations

impl<V> TtlEntry<V>

pub fn new(value: V, inserted_at_secs: u64, ttl_secs: u64) -> Self

Create a new entry with the given parameters.

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

Returns true when now_secs has passed the entry’s deadline.

A TTL of 0 means the entry never expires.

pub fn remaining_secs(&self, now_secs: u64) -> u64

Seconds remaining before expiry, saturating at zero once expired.

Returns u64::MAX for entries with TTL == 0 (no expiry).
