Struct questdb::ingress::TimestampNanos

pub struct TimestampNanos(/* private fields */);

A i64 timestamp expressed as nanoseconds since the UNIX epoch (UTC).

Examples

use questdb::ingress::TimestampNanos;

let ts = TimestampNanos::now();

or

use questdb::ingress::TimestampNanos;

let ts = TimestampNanos::new(1659548315647406592);

or

use questdb::ingress::TimestampNanos;

let ts = TimestampNanos::from_systemtime(std::time::SystemTime::now())?;

or

use questdb::ingress::TimestampNanos;

let ts = TimestampNanos::from_datetime(chrono::Utc::now());

Implementations

impl TimestampNanos
