Struct TimestampedValue 

pub struct TimestampedValue {
    pub value: Vec<u8>,
    pub timestamp: u64,
}

A value with an embedded timestamp for LWW ordering.

Used with the Last-Writer-Wins merge strategy to determine which value should win when concurrent modifications occur.

Serialization Format

Values are serialized as: [value bytes][8-byte big-endian timestamp]

Example

use prolly::TimestampedValue;

let tv = TimestampedValue::now(b"hello".to_vec());
let bytes = tv.to_bytes();
let restored = TimestampedValue::from_bytes(&bytes).unwrap();
assert_eq!(restored.value, b"hello");

Fields

value: Vec<u8>

The actual value bytes

timestamp: u64

Timestamp in microseconds since epoch

Implementations

impl TimestampedValue

pub fn new(value: Vec<u8>, timestamp: u64) -> Self

Create a new timestamped value with the given timestamp.

pub fn now(value: Vec<u8>) -> Self

Create a new timestamped value with current time.

pub fn to_bytes(&self) -> Vec<u8>

Serialize to bytes (value + 8-byte timestamp suffix).

Format: [value bytes][8-byte big-endian timestamp]

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Deserialize from bytes.

Returns None if the byte slice is too short (< 8 bytes).
