Struct TempoSegment 

pub struct TempoSegment {
    pub start_tick: u64,
    pub us_per_quarter: u32,
}

One constant-tempo span of a MIDI TempoMap, starting at a tick offset.

A segment holds the tempo (in microseconds per quarter note) that applies from start_tick until the next segment begins. The tempo must be non-zero.

Examples

use sim_lib_stream_clock::TempoSegment;

let segment = TempoSegment::new(0, 500_000)?;
assert_eq!(segment.start_tick, 0);
assert_eq!(segment.us_per_quarter, 500_000);

Fields

start_tick: u64

Tick offset at which this tempo takes effect.

us_per_quarter: u32

Tempo of the segment, in microseconds per quarter note.

Implementations

impl TempoSegment

pub fn new(start_tick: u64, us_per_quarter: u32) -> Result<Self>

Builds a tempo segment beginning at start_tick.

Returns an error when us_per_quarter is zero.

Trait Implementations

impl Clone for TempoSegment

fn clone(&self) -> TempoSegment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TempoSegment

impl Debug for TempoSegment

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

Formats the value using the given formatter.

impl Eq for TempoSegment

impl PartialEq for TempoSegment

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