Struct EngineConfig 

pub struct EngineConfig {
    pub buffer_size: u32,
    pub sample_rate: u32,
}

Configuration for the audio engine.

Fields

buffer_size: u32

Audio buffer size in samples. Lower = less latency, more CPU. Typical values: 32, 64, 128, 256, 512.

sample_rate: u32

Sample rate in Hz. Typical values: 44100, 48000, 96000.

Implementations

impl EngineConfig

pub fn buffer_duration_secs(&self) -> f64

Buffer duration in seconds.

pub fn buffer_duration_ms(&self) -> f64

Buffer duration in milliseconds.

Trait Implementations

impl Clone for EngineConfig

fn clone(&self) -> EngineConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EngineConfig

impl Debug for EngineConfig

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

Formats the value using the given formatter.

impl Default for EngineConfig

fn default() -> Self

The numbers to run at when there is no device to ask — --no-audio, or a backend that would not open.

Deliberately not the general-purpose starting point it looks like. As soon as a device is open, the config comes from the device via From<StreamFormat>; reaching for this instead is how an engine ends up at a rate the stream is not running at. It is here for the case where nothing is listening, and in that case the numbers only have to be self-consistent.

impl<'de> Deserialize<'de> for EngineConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EngineConfig

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 From<StreamFormat> for EngineConfig

fn from(format: StreamFormat) -> Self

The config the engine must be built from once a device has been opened.

buffer_size falls back to the largest block the device may deliver when the device was left to choose its own: nothing sizes a buffer from this field any more — the mixer takes max_buffer_frames directly — so the honest value for a block size we were never told is the worst case rather than a guess.

impl PartialEq for EngineConfig

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for EngineConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
