Struct ibc_core::primitives::Timestamp

pub struct Timestamp { /* private fields */ }

A new type wrapper over Option<Time> to keep track of IBC packet timeout.

We use an explicit Option type to distinguish this when converting between a u64 value and a raw timestamp. In protocol buffer, the timestamp is represented as a u64 Unix timestamp in nanoseconds, with 0 representing the absence of timestamp.

Implementations

impl Timestamp

pub fn from_nanoseconds( nanoseconds: u64 ) -> Result<Timestamp, ParseTimestampError>

The IBC protocol represents timestamps as u64 Unix timestamps in nanoseconds.

A protocol value of 0 indicates that the timestamp is not set. In this case, our domain type takes the value of None.

pub fn now() -> Timestamp

Returns a Timestamp representation of the current time.

pub fn none() -> Timestamp

Returns a Timestamp representation of a timestamp not being set.

pub fn duration_since(&self, other: &Timestamp) -> Option<Duration>

Computes the duration difference of another Timestamp from the current one. Returns the difference in time as an core::time::Duration. Returns None if the other Timestamp is more advanced than the current or if either of the Timestamps is not set.

pub fn as_nanoseconds(&self) -> u64

👎Deprecated since 0.9.1: use nanoseconds instead

Convert a Timestamp to u64 value in nanoseconds. If no timestamp is set, the result is 0.

pub fn nanoseconds(self) -> u64

Convert a Timestamp to u64 value in nanoseconds. If no timestamp is set, the result is 0.

use ibc_primitives::Timestamp;

let max = u64::MAX;
let tx = Timestamp::from_nanoseconds(max).unwrap();
let utx = tx.nanoseconds();
assert_eq!(utx, max);
let min = u64::MIN;
let ti = Timestamp::from_nanoseconds(min).unwrap();
let uti = ti.nanoseconds();
assert_eq!(uti, min);
let tz = Timestamp::default();
let utz = tz.nanoseconds();
assert_eq!(utz, 0);

pub fn into_datetime(self) -> Option<OffsetDateTime>

Convert a Timestamp to an optional [OffsetDateTime]

pub fn into_tm_time(self) -> Option<Time>

Convert a Timestamp to an optional [tendermint::Time]

pub fn check_expiry(&self, other: &Timestamp) -> Expiry

Checks whether the timestamp has expired when compared to the other timestamp. Returns an Expiry result.

pub fn is_set(&self) -> bool

Checks whether the timestamp is set.
