Enum cpal::PauseStreamError

pub enum PauseStreamError {
    DeviceNotAvailable,
    BackendSpecific {
        err: BackendSpecificError,
    },
}

Errors that might occur when calling pause_stream.

As of writing this, only macOS may immediately return an error while calling this method. This is because both the alsa and wasapi backends only enqueue these commands and do not process them immediately.

Variants

DeviceNotAvailable

The device associated with the stream is no longer available.

BackendSpecific

See the BackendSpecificError docs for more information about this error variant.

Fields of BackendSpecific

err: BackendSpecificError

impl Error for PauseStreamError

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)

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
