Struct AudioRequest 

pub struct AudioRequest {
    pub sample_rate: Option<u32>,
    pub buffer_size: Option<u32>,
}

What the command line asked for. Both halves optional, and unspecified is the ordinary case.

Separate from EngineConfig because they are different facts: this is a request, that is what the engine runs at. Collapsing the two is what let an engine synthesising at 44100 feed a stream running at 48000 — every note 1.47 semitones sharp, 120 BPM playing back at 130.6.

None means follow the device. That is the default because on CoreAudio pinning a sample rate changes the machine’s nominal rate for every other application too, and opening a DAW is not consent to that.

Fields

sample_rate: Option<u32>

Sample rate in Hz, or None to run at whatever the device is set to.

buffer_size: Option<u32>

Block size in samples, or None to let the device choose.

Implementations

impl AudioRequest

pub const fn follow_device() -> Self

Ask for nothing and take what the device is already doing.

pub fn without_device(self) -> EngineConfig

The config to run at when there is no device to follow. Anything the command line named is honoured; the rest comes from EngineConfig::default.

Trait Implementations

impl Clone for AudioRequest

fn clone(&self) -> AudioRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AudioRequest

impl Debug for AudioRequest

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

Formats the value using the given formatter.

impl Default for AudioRequest

fn default() -> AudioRequest

Returns the “default value” for a type.

impl Eq for AudioRequest

impl From<EngineConfig> for AudioRequest

fn from(config: EngineConfig) -> Self

“Run at exactly this” as a request. Used by callers that already hold concrete numbers — the headless test apps, which open no device at all.

impl PartialEq for AudioRequest

fn eq(&self, other: &AudioRequest) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
