Struct PrefixInfo 

#[non_exhaustive]
pub struct PrefixInfo {
    pub keys: u64,
    pub expires: u64,
}

Per-prefix keyspace stats from Store::info_prefix.

let store = kevy_embedded::Store::open(kevy_embedded::Config::default())?;
store.set(b"user:1", b"a")?;
store.set(b"order:1", b"b")?;
let info = store.info_prefix(b"user:");
assert_eq!((info.keys, info.expires), (1, 0));

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

keys: u64

Live keys under the prefix.

let store = kevy_embedded::Store::open(kevy_embedded::Config::default())?;
store.set(b"user:1", b"a")?;
store.set(b"user:2", b"b")?;
store.set(b"order:1", b"c")?;
assert_eq!(store.info_prefix(b"user:").keys, 2);

expires: u64

How many of them carry a TTL.

let store = kevy_embedded::Store::open(kevy_embedded::Config::default())?;
store.set(b"s:1", b"a")?;
store.set_with_ttl(b"s:2", b"b", std::time::Duration::from_secs(60))?;
assert_eq!(store.info_prefix(b"s:").expires, 1);
