Enum OutputError 

#[non_exhaustive]
pub enum OutputError {
    NoDevice,
    Unavailable(String),
    Device(String),
}

Why an output didn’t open.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoDevice

There is nothing to play on.

Unavailable(String)

This target has no way out yet, or this page can’t use one.

Device(String)

The device or the system refused.

Trait Implementations

impl Eq for OutputError

impl Error for OutputError

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

Returns 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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for OutputError

fn eq(&self, other: &OutputError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
