Struct CpalInputConfig 

pub struct CpalInputConfig {
    pub host: Option<HostId>,
    pub device_id: Option<DeviceId>,
    pub desired_block_frames: Option<u32>,
    pub channel_config: ResamplingChannelConfig,
    pub fallback: bool,
    pub fail_on_no_input: bool,
}

The configuration of an input audio stream in the CPAL backend.

Fields

host: Option<HostId>

The host to use. Set to None to use the system’s default audio host.

device_id: Option<DeviceId>

The id of the input device to use. Set to None to use the system’s default input device.

By default this is set to None.

desired_block_frames: Option<u32>

The latency/block size of the audio stream to use. Set to None to use the device’s default value.

Smaller values may give better latency, but is not supported on all platforms and may lead to performance issues.

This currently has no effect on iOS platforms.

By default this is set to Some(1024).

channel_config: ResamplingChannelConfig

The configuration of the input to output stream channel.

fallback: bool

Whether or not to fall back to the default device if a device with the given configuration could not be found.

By default this is set to true.

fail_on_no_input: bool

If true, then an error will be returned if an input stream could not be started. If false, then the output stream will still attempt to start with no input stream.

By default this is set to false.

Trait Implementations

impl Clone for CpalInputConfig

fn clone(&self) -> CpalInputConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CpalInputConfig

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

Formats the value using the given formatter.

impl Default for CpalInputConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CpalInputConfig

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