Struct OscTime 

pub struct OscTime {
    pub seconds: u32,
    pub fractional: u32,
}

A time tag in OSC message consists of two 32-bit integers where the first one denotes the number of seconds since 1900-01-01 and the second the fractions of a second. For details on its semantics see http://opensoundcontrol.org/node/3/#timetags

Examples

#[cfg(feature = "std")]
{
    use rosc::OscTime;
    use std::{convert::TryFrom, time::UNIX_EPOCH};

    assert_eq!(
        OscTime::try_from(UNIX_EPOCH).unwrap(),
        OscTime::from((2_208_988_800, 0))
    );
}

Conversions between (u32, u32)

Prior to version 0.5.0 of this crate, OscTime was defined as a type alias to (u32, u32). If you are upgrading from one of these older versions, you can use .into() to convert between (u32, u32) and OscTime in either direction.

Conversions between std::time::SystemTime

The traits in std::convert are implemented for converting between SystemTime and OscTime in both directions. An OscTime can be converted into a SystemTime using From/Into. A SystemTime can be converted into an OscTime using TryFrom/TryInto. The fallible variants of the conversion traits are used this case because not every SystemTime can be represented as an OscTime.

These conversions are lossy, but are tested to have a deviation within 5 nanoseconds when converted back and forth in either direction.

Although any time since the OSC epoch (1900-01-01 00:00:00 UTC) can be represented using the OSC timestamp format, this crate only allows conversions between times greater than or equal to the UNIX_EPOCH. This allows the math used in the conversions to work on 32-bit systems which cannot represent times that far back.

impl Ord for OscTime

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

This method returns an Ordering between self and other.

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