Struct JackTransportState 

pub struct JackTransportState { /* private fields */ }

Snapshot of JACK transport state for one process callback.

Implementations

impl JackTransportState

pub fn stopped(sample_pos: u64) -> Self

Builds a stopped transport at sample_pos with a default 120 BPM tempo and a zero PPQ position.

pub fn rolling(sample_pos: u64, tempo_bpm: f64, ppq_pos: f64) -> Result<Self>

Builds a rolling transport at sample_pos with the given tempo and PPQ position.

Errors

Returns an error when tempo_bpm is non-finite or not positive, or when ppq_pos is non-finite.

pub fn rolling_flag(self) -> bool

Returns whether the transport is rolling (playing).

pub fn sample_pos(self) -> u64

Returns the transport position in sample frames.

pub fn tempo_bpm(self) -> f64

Returns the transport tempo in beats per minute.

pub fn ppq_pos(self) -> f64

Returns the transport position in pulses per quarter note.

pub fn to_graph_transport(self) -> Transport

Converts this snapshot into the audio-graph Transport consumed by a process block.

Trait Implementations

impl Clone for JackTransportState

fn clone(&self) -> JackTransportState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JackTransportState

impl Debug for JackTransportState

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

Formats the value using the given formatter.

impl PartialEq for JackTransportState

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