Struct ScmCacheEntry 

pub struct ScmCacheEntry {
    pub key: ScmCacheKey,
    pub result: Vec<u8>,
    pub inserted_at: u64,
    pub last_accessed: u64,
    pub access_count: u64,
    pub ttl_us: Option<u64>,
    pub similarity_score: f64,
}

A single cached result, keyed by a ScmCacheKey.

Fields

key: ScmCacheKey

The cache key (query text + embedding + hash).

result: Vec<u8>

Serialised result payload.

inserted_at: u64

Microsecond timestamp when this entry was inserted (caller-supplied).

last_accessed: u64

Microsecond timestamp of the last access (updated on every hit).

access_count: u64

How many times this entry has been accessed (hits).

ttl_us: Option<u64>

Optional TTL in microseconds from inserted_at; None = immortal.

similarity_score: f64

Similarity of the original query to itself — always 1.0 at insertion.
