Enum cpal::DefaultStreamConfigError

pub enum DefaultStreamConfigError {
    DeviceNotAvailable,
    StreamTypeNotSupported,
    BackendSpecific {
        err: BackendSpecificError,
    },
}

May occur when attempting to request the default input or output stream format from a Device.

Variants

DeviceNotAvailable

StreamTypeNotSupported

Returned if e.g. the default input format was requested on an output-only audio device.

impl Error for DefaultStreamConfigError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<BackendSpecificError> for DefaultStreamConfigError

fn from(source: BackendSpecificError) -> Self

Performs the conversion.
