Struct cpal::BackendSpecificError

pub struct BackendSpecificError {
    pub description: String,
}

Some error has occurred that is specific to the backend from which it was produced.

This error is often used as a catch-all in cases where:

• It is unclear exactly what error might be produced by the backend API.
• It does not make sense to add a variant to the enclosing error type.
• No error was expected to occur at all, but we return an error to avoid the possibility of a panic! caused by some unforeseen or unknown reason.

Note: If you notice a BackendSpecificError that you believe could be better handled in a cross-platform manner, please create an issue or submit a pull request with a patch that adds the necessary error variant to the appropriate error enum.

Trait Implementations

impl Clone for BackendSpecificError

fn clone(&self) -> BackendSpecificError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BackendSpecificError

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

Formats the value using the given formatter.

impl Error for BackendSpecificError

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

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

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
