Struct fog_pack::types::Timestamp

pub struct Timestamp { /* fields omitted */ }

Structure for holding a raw fog-pack timestamp. This stores time in some consistent internal format, which may or may not be UTC. UTC time can always be extracted from it.

Implementations

impl Timestamp

pub fn from_utc(sec: i64, nano: u32) -> Option<Timestamp>

Create a timestamp from a raw seconds + nanoseconds value

pub fn from_sec(sec: i64) -> Timestamp

pub const fn zero() -> Timestamp

Zero time - UTC epoch time

pub const fn min_value() -> Timestamp

Minimum possible time that can be represented

pub const fn max_value() -> Timestamp

Maximum possible time that can be represented

pub fn min(self, other: Timestamp) -> Timestamp

pub fn max(self, other: Timestamp) -> Timestamp

pub fn next(self) -> Timestamp

Add 1 nanosecond to timestamp. Will go into leap second (nanoseconds > 1e6) before it goes to the next second.

pub fn prev(self) -> Timestamp

Subtract 1 nanosecond from timestamp. Will go into leap second (nanoseconds > 1e6) when it must decrement a second.

pub fn timestamp_utc(&self) -> i64

Return the UNIX timestamp (number of seconds since January 1, 1970 0:00:00 UTC). As a reminder, this is UTC time and thus includes leap seconds.

pub fn timestamp_subsec_nanos(&self) -> u32

Returns the number of nanoseconds past the second count.

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

Convert into a byte vector. For extending an existing byte vector, see encode_vec.

pub fn encode_vec(&self, vec: &mut Vec<u8>)

Encode onto a byte vector one of 3 formats:

1. If nanoseconds is nonzero, encode the standard byte, the seconds as little-endian i64, and the nanoseconds as little-endian u32.
2. If nanoseconds is zero & seconds maps to a u32, encode the standard byte, and the seconds as little-endian u32.
3. If nanoseconds is zero & seconds does not map to a u32, encode the standard byte, and the seconds as little-endian i64.

pub fn size(&self) -> usize

pub fn now() -> Option<Timestamp>

Create a Timestamp based on the current system time. Can fail if the system clock is extremely wrong - the time is before Unix Epoch, or nanosecond portion is greater than 2 seconds.
