Struct Timestamp 

#[repr(transparent)]
pub struct Timestamp<T = u128>(pub T);

Timestamp is a generic implementation of a type that represents some point in time.

Basic Usage

use scsys_time::Timestamp;

let ts = Timestamp::<u128>::now();
println!("Current Timestamp: {}", ts);

Features

The timestamps implementation dynamically reflects the extensive feature-gating of the crate. Listed below are the features that customize the behavior of the Timestamp type:

• serde: Enables serialization and deserialization of the Timestamp type.

• chrono: Enables support for chrono timestamps, uses i64 for the [Now] impl

• std: Enables the use of system time for the default implementation of:

  • Timestamp<u64>: for seconds
  • Timestamp<u128>: for milliseconds

Tuple Fields

0: T
