Enum InitError 

pub enum InitError {
    UnsupportedPlatform,
    InvalidModelRoot,
    NeuralEngineUnavailable,
}

Failure to initialize a Core ML backend instance.

Variants

UnsupportedPlatform

The backend is only executable on macOS 14 or newer.

InvalidModelRoot

The configured model root is missing, not a directory, or not representable as UTF-8.

NeuralEngineUnavailable

Core ML does not report an accessible Apple Neural Engine.

Trait Implementations

impl Clone for InitError

fn clone(&self) -> InitError

impl Copy for InitError

impl Debug for InitError

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

Formats the value using the given formatter.

impl Eq for InitError

impl Error for InitError

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 InitError

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

Equality operator ==.

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

Inequality operator !=.
