Enum FeatureError 

#[non_exhaustive]
pub enum FeatureError {
    Disabled,
    Unsupported,
}

Feature availability failure.

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.

Disabled

The feature is intentionally not enabled for this build or context.

Unsupported

The feature is not implemented by this crate version.

Trait Implementations

impl Clone for FeatureError

fn clone(&self) -> FeatureError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FeatureError

impl Debug for FeatureError

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

Formats the value using the given formatter.

impl Display for FeatureError

impl Eq for FeatureError

impl PartialEq for FeatureError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
