pub enum FeatureError {
    NotEnabled {
        feature: String,
        operation: String,
    },
    MultipleRequired {
        operation: String,
        required_features: String,

    },
    Misconfigured {
        feature: String,
        reason: String,
    },
}

Errors related to missing or disabled cargo features.

This covers cases where optional functionality was used but the required cargo feature wasn’t enabled at compile time.

Variants

NotEnabled

A cargo feature is required but not enabled.

Fields

feature: String

The cargo feature that needs to be enabled.

operation: String

The operation that requires this feature.

MultipleRequired

Multiple features are required but some are missing.

Fields

operation: String

The operation requiring multiple features.

required_features: String

Comma-separated list of required features.

enabled_features: String

Comma-separated list of currently enabled features.

Misconfigured

A feature is enabled but its dependencies are not properly configured.

Fields

feature: String

The misconfigured feature.

reason: String

Explanation of the configuration issue.

Implementations

impl FeatureError

pub fn not_enabled<F, O>(feature: F, operation: O) -> Self

where F: ToString, O: ToString,

Create a new feature not enabled error.

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 Debug for FeatureError

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

Formats the value using the given formatter.

impl Display for FeatureError

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

Formats the value using the given formatter.

impl Error for FeatureError

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 From<FeatureError> for AudioSampleError

fn from(source: FeatureError) -> Self

Converts to this type from the input type.
