Enum DeviceDirection 

#[non_exhaustive]
pub enum DeviceDirection {
    Input,
    Output,
    Duplex,
    Unknown,
}

The direction(s) that a device supports.

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.

Input

Input only (capture/recording)

Output

Output only (playback/rendering)

Duplex

Both input and output

Unknown

Direction unknown or not yet determined
