Struct Record 

pub struct Record {
    pub key: Vec<u8>,
    pub ts: i64,
    pub expire_at: i64,
    pub value: Vec<u8>,
}

A single key-value record in the LSM engine.

Each record has a binary key, a microsecond-precision ts timestamp, an expire_at time (in microseconds since epoch), and a binary value. Records with expire_at <= now are skipped by queries and eventually garbage-collected.

Fields

key: Vec<u8>

Binary key. Use Record::key_str for lossy UTF-8 display.

ts: i64

Microsecond timestamp (e.g. SystemTime::now() as microseconds since Unix epoch).

expire_at: i64

Expiration time in microseconds since Unix epoch. Use i64::MAX for records that should never expire.

value: Vec<u8>

Binary payload. Any byte sequence is accepted.

Implementations

impl Record

pub fn new(key: impl Into<Vec<u8>>, ts: i64, value: Vec<u8>) -> Self

Convenience constructor mirroring the old String-keyed API.

pub fn key_str(&self) -> Cow<'_, str>

View the key as a UTF-8 string slice when callers know keys are text. Returns the raw bytes as a lossy string for non-UTF-8 keys.

Trait Implementations

impl Clone for Record

fn clone(&self) -> Record

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Record

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Record

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Record

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
