Enum TimeUnit 

pub enum TimeUnit {
    NanoSeconds,
    MicroSeconds,
    MilliSeconds,
    Seconds,
    Minutes,
    Hours,
    Days,
}

A unit of time, from nanoseconds to days.

Time units are used to display timings and speeds. Usually the most convenient unit is chosen automatically, but you can fix a specific unit with ProgressLog::time_unit.

Variants

NanoSeconds

A nanosecond (10⁻⁹ seconds).

MicroSeconds

A microsecond (10⁻⁶ seconds).

MilliSeconds

A millisecond (10⁻³ seconds).

Seconds

A second.

Minutes

A minute (60 seconds).

Hours

An hour (3600 seconds).

Days

A day (86400 seconds).

Implementations

impl TimeUnit

pub const VALUES: [TimeUnit; 7]

All time units, in increasing order of duration.

pub const fn label(&self) -> &'static str

Returns the label used to display this time unit (e.g., s for Seconds).

pub const fn as_seconds(&self) -> f64

Returns the length of this time unit in seconds.

pub const fn nice_time_unit(seconds: f64) -> Self

Returns the largest time unit not exceeding the given duration in seconds; it is used to display per-item timings.

For durations shorter than a nanosecond, NanoSeconds is returned.

pub const fn nice_speed_unit(seconds: f64) -> Self

Returns the smallest time unit, starting from Seconds, in which an activity taking the given number of seconds per item progresses at a speed of at least one item per unit; it is used to display speeds.

For activities slower than one item per day, Days is returned.

pub fn pretty_print(milliseconds: u128) -> String

Pretty-prints a duration expressed in milliseconds.

Durations of less than a second are displayed as {}ms; longer durations are displayed as days, hours, minutes, and seconds (e.g., 1d 3h 10m 5s), discarding the sub-second part.

Trait Implementations

impl Clone for TimeUnit

fn clone(&self) -> TimeUnit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TimeUnit

impl Debug for TimeUnit

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

Formats the value using the given formatter.
