Struct TimeBase

pub struct TimeBase {
    pub numer: u32,
    pub denom: u32,
}

A TimeBase is the conversion factor between time, expressed in seconds, and a TimeStamp or Duration.

In other words, a TimeBase is the length in seconds of one tick of a TimeStamp or Duration.

Fields

numer: u32

The numerator.

denom: u32

The denominator.

Implementations

impl TimeBase

pub fn new(numer: u32, denom: u32) -> Self

Creates a new TimeBase. Panics if either the numerator or denominator is 0.

pub fn calc_time(&self, ts: TimeStamp) -> Time

Accurately calculates a Time using the TimeBase and the provided TimeStamp. On overflow, the seconds field of Time wraps.

pub fn calc_timestamp(&self, time: Time) -> TimeStamp

Accurately calculates a TimeStamp from the given Time using the TimeBase as the conversion factor. On overflow, the TimeStamp wraps.

Trait Implementations

impl Clone for TimeBase

fn clone(&self) -> TimeBase

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimeBase

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

Formats the value using the given formatter.

impl Default for TimeBase

fn default() -> TimeBase

Returns the “default value” for a type.

impl Display for TimeBase

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

Formats the value using the given formatter.

impl From<TimeBase> for f64

fn from(timebase: TimeBase) -> Self

Converts to this type from the input type.

impl Ord for TimeBase

fn cmp(&self, other: &TimeBase) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TimeBase

fn eq(&self, other: &TimeBase) -> 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.

impl PartialOrd for TimeBase

fn partial_cmp(&self, other: &TimeBase) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
