Enum Unit 

pub enum Unit {
    Seconds,
    Millis,
    Micros,
    HundredNanos,
    Nanos,
    Days,
}

The tick unit a format counts in.

Variants

Seconds

Whole seconds.

Millis

Milliseconds (Java/JS).

Micros

Microseconds (Chrome/WebKit, PostgreSQL).

HundredNanos

100-nanosecond intervals (FILETIME, .NET ticks).

Nanos

Nanoseconds (APFS, Unix-ns).

Days

Whole days (OLE Automation / Excel serial — usually fractional).

Implementations

impl Unit

pub const fn nanos(self) -> i128

Nanoseconds per tick of this unit.

pub const fn sub_second_digits(self) -> u32

Decimal digits of sub-second resolution this unit can express (seconds/days → 0, millis → 3, micros → 6, 100-nanos → 7, nanos → 9). Drives auto-detect granularity scoring: a whole-second raw value is a poor fit for a finer unit, so it is penalised, never hidden.

Trait Implementations

impl Clone for Unit

fn clone(&self) -> Unit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Unit

impl Debug for Unit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Unit

impl PartialEq for Unit

fn eq(&self, other: &Unit) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
