Struct SoftwareParameters 

pub struct SoftwareParameters { /* private fields */ }

Available on crate feature alsa only.

Collection of software parameters being configured for a Pcm handle.

See Pcm::software_parameters.

Implementations

impl SoftwareParameters

pub fn copy(&mut self, other: &SoftwareParameters)

Copy one set of software parameters to another.

Examples

use audio_device::alsa;

let mut a = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let mut b = alsa::Pcm::open_default(alsa::Stream::Playback)?;

let a = a.software_parameters()?;
let mut b = b.software_parameters()?;

b.copy(&a);

pub fn boundary(&self) -> Result<c_ulong>

Get boundary for ring pointers from a software configuration container.

Examples

use audio_device::alsa;

let mut pcm = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let sw = pcm.software_parameters()?;

let boundary = sw.boundary()?;
dbg!(boundary);

pub fn timestamp_mode(&self) -> Result<Timestamp>

Get timestamp mode from a software configuration container.

Examples

use audio_device::alsa;

let mut pcm = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let sw = pcm.software_parameters()?;

let timestamp_mode = sw.timestamp_mode()?;
dbg!(timestamp_mode);

pub fn timestamp_type(&self) -> Result<TimestampType>

Get timestamp type from a software configuration container.

Examples

use audio_device::alsa;

let mut pcm = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let sw = pcm.software_parameters()?;

let value = sw.timestamp_type()?;
dbg!(value);

pub fn available_min(&self) -> Result<c_ulong>

Get avail min from a software configuration container.

Examples

use audio_device::alsa;

let mut pcm = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let sw = pcm.software_parameters()?;

let available_min = sw.available_min()?;
dbg!(available_min);

pub fn period_event(&self) -> Result<c_int>

Get period event from a software configuration container.

Examples

use audio_device::alsa;

let mut pcm = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let sw = pcm.software_parameters()?;

let value = sw.period_event()?;

pub fn start_threshold(&self) -> Result<c_ulong>

Get start threshold from a software configuration container.

Examples

use audio_device::alsa;

let mut pcm = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let sw = pcm.software_parameters()?;

let value = sw.start_threshold()?;

pub fn stop_threshold(&self) -> Result<c_ulong>

Get stop threshold from a software configuration container.

Examples

use audio_device::alsa;

let mut pcm = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let sw = pcm.software_parameters()?;

let value = sw.stop_threshold()?;

pub fn silence_threshold(&self) -> Result<c_ulong>

Get silence threshold from a software configuration container.

A portion of playback buffer is overwritten with silence (see set_silence_size) when playback underrun is nearer than silence threshold.

Examples

use audio_device::alsa;

let mut pcm = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let sw = pcm.software_parameters()?;

let value = sw.silence_threshold()?;

pub fn silence_size(&self) -> Result<c_ulong>

Get silence size from a software configuration container.

Examples

use audio_device::alsa;

let mut pcm = alsa::Pcm::open_default(alsa::Stream::Playback)?;
let sw = pcm.software_parameters()?;

let value = sw.silence_size()?;

Trait Implementations

impl Drop for SoftwareParameters

fn drop(&mut self)

Executes the destructor for this type.
