Struct scribl_curves::TimeDiff

pub struct TimeDiff(_);

The difference between two Times. Unlike std::time::Duration, this can be negative.

Implementations

impl TimeDiff

pub const ZERO: TimeDiff

pub fn as_audio_idx(&self, sample_rate: u32) -> isize

Interpreting self as the offset from the beginning of an audio buffer, return the corresponding index into that buffer. Note that the return value is signed, because a negative offset from the beginning of an audio buffer corresponds to a negative index.

Examples

use scribl_curves::Time;
assert_eq!((Time::ZERO - Time::ZERO).as_audio_idx(44100), 0);
assert_eq!((Time::from_micros(1000000) - Time::ZERO).as_audio_idx(44100), 44100);
assert_eq!((Time::ZERO - Time::from_micros(1000000)).as_audio_idx(44100), -44100);

pub fn from_audio_idx(idx: i64, sample_rate: u32) -> TimeDiff

pub const fn as_micros(self) -> i64

pub const fn from_micros(us: i64) -> TimeDiff
