Macro from_sec_f 

macro_rules! from_sec_f {
    ($sec:expr, on=$scale:expr, target=$target:expr) => { ... };
    ($sec:expr, target=$target:expr, on=$scale:expr) => { ... };
    ($sec:expr, on=$scale:expr) => { ... };
    ($sec:expr, target=$target:expr) => { ... };
    ($sec:expr) => { ... };
}

Builds a Dt from a floating-point seconds count with optional scale labels.

• Equivalent to Dt::from_sec_f.
• Does not perform time-scale conversion.

Defaults

Omitted	Default
on and target	both Scale::TAI
only on=s	target=s
only target=t	on=TAI

Forms

Form	Meaning
from_sec_f!(sec)	both scales TAI
from_sec_f!(sec, on=s)	scale and target s
from_sec_f!(sec, target=t)	scale TAI, target t
from_sec_f!(sec, on=s, target=t)	either order
from_sec_f!(sec, target=t, on=s)	either order

Examples

use deep_time::Scale;
use deep_time::from_sec_f;

let a = from_sec_f!(5.5);
let b = from_sec_f!(0.0, on=Scale::UTC);
let c = from_sec_f!(1.0, on=Scale::TAI, target=Scale::UTC);
let d = from_sec_f!(1.0, target=Scale::UTC, on=Scale::TAI);

assert_eq!(a, deep_time::Dt::from_sec_f(5.5, Scale::TAI, Scale::TAI));
assert_eq!(b, deep_time::Dt::from_sec_f(0.0, Scale::UTC, Scale::UTC));
assert_eq!(c, deep_time::Dt::from_sec_f(1.0, Scale::TAI, Scale::UTC));
assert_eq!(d, c);
