Enum Unavailability 

#[non_exhaustive]
pub enum Unavailability {
    DeviceNotEligible,
    AppleIntelligenceNotEnabled,
    ModelNotReady,
    OsTooOld,
    Unknown,
}

Reason why SystemLanguageModel is unavailable.

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.

DeviceNotEligible

The hardware does not support Apple Intelligence (e.g. Intel Mac, M1).

AppleIntelligenceNotEnabled

Apple Intelligence is supported but disabled in System Settings.

ModelNotReady

Model assets are still downloading.

OsTooOld

The host OS is older than macOS 26.0.

Unknown

FoundationModels reported an unavailability reason this crate doesn’t recognise — most likely added in a newer SDK.

Trait Implementations

impl Clone for Unavailability

fn clone(&self) -> Unavailability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Unavailability

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

Formats the value using the given formatter.

impl PartialEq for Unavailability

fn eq(&self, other: &Unavailability) -> 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.
