Struct CoreAudioTiming 

pub struct CoreAudioTiming { /* private fields */ }

Timing metadata accepted by a CoreAudio render callback.

Implementations

impl CoreAudioTiming

pub fn new( sample_rate_hz: u32, buffer_frames: usize, input_latency_frames: u32, output_latency_frames: u32, ) -> Result<Self>

Builds timing metadata from a sample rate, buffer size, and the input and output latencies, all measured in frames.

Returns an error when the sample rate or buffer size is zero.

Examples

use sim_lib_stream_coreaudio::CoreAudioTiming;

let timing = CoreAudioTiming::new(48_000, 128, 128, 128).unwrap();
assert_eq!(timing.sample_rate_hz(), 48_000);
assert!(CoreAudioTiming::new(0, 128, 0, 0).is_err());

pub fn default_low_latency() -> Self

Returns a default low-latency timing: 48 kHz, 128-frame buffer, and 128-frame input and output latencies.

pub fn sample_rate_hz(self) -> u32

Returns the sample rate in hertz.

pub fn buffer_frames(self) -> usize

Returns the callback buffer size in frames.

pub fn input_latency_frames(self) -> u32

Returns the input latency in frames.

pub fn output_latency_frames(self) -> u32

Returns the output latency in frames.

Trait Implementations

impl Clone for CoreAudioTiming

fn clone(&self) -> CoreAudioTiming

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CoreAudioTiming

impl Debug for CoreAudioTiming

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

Formats the value using the given formatter.

impl Eq for CoreAudioTiming

impl PartialEq for CoreAudioTiming

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