Struct MLModelError

#[repr(transparent)]
pub struct MLModelError(pub NSInteger);

Available on crate feature MLModelError only.

MLModelError defines the set of MLModel related error codes.

The framework communicates the error code to the application through NSError’s code property. The application could use the error code to present an helpful error message to the user or to diagnose the problem.

See also NSError’s localizedDescription property, which often contains more detailed information.

Implementations

impl MLModelError

pub const Generic: Self

Core ML throws/returns this error when the framework encounters an generic error.

The typical cause for this error is an unexpected framework level problem.

pub const FeatureType: Self

Core ML throws/returns this error when the model client, typically an application, sends the wrong feature type to a model’s input.

The typical cause for this error is a programming mistake.

For example, a prediction method will throw/return the error when the caller passes an image to a model’s input that expects an MLMultiArray.

pub const IO: Self

Core ML throws/returns this error when the framework encounters some I/O problem, most likely a file I/O problem.

For example, a model loading will throw/return the error when the caller requests a non-existing model URL.

pub const CustomLayer: Self

Core ML throws/returns this error when the framework encounters an error in the custom layer subsystem.

The typical cause for this error is a programming mistake.

For example, a prediction method will throw/return the error when it fails to find the custom layer implementation.

pub const CustomModel: Self

Core ML throws/returns this error when the framework encounters an error in the custom model subsystem.

The typical cause for this error is a programming mistake.

For example, a prediction method will throw/return the error when it fails to find the custom model implementation.

pub const Update: Self

Core ML throws/returns this error when the framework encounters an error while performing the on-device model update.

For example, the framework will throw/return the error when it fails to save the updated model.

pub const Parameters: Self

Core ML throws/returns this error when the model client, typically an application, queries an unsupported model parameter (see MLParameterKey).

The typical cause for this error is a programming mistake.

pub const ModelDecryptionKeyFetch: Self

Core ML throws/returns this error when the framework fails to download the model decryption key.

The typical cause for this error is a network connection issue to the key server.

pub const ModelDecryption: Self

Core ML throws/returns this error when the framework encounters an error in the model decryption subsystem.

The typical cause for this error is in the key server configuration and the client application cannot do much about it.

For example, a model loading method will throw/return the error when it uses incorrect model decryption key.

pub const ModelCollection: Self

Core ML throws/returns this error when the framework encounters an error in the model collection deployment subsystem.

The typical cause for this error is the network connectability issue to the model deployment server.

pub const PredictionCancelled: Self

Core ML throws/returns this error when the prediction is cancelled prior to completing.

Trait Implementations

impl Clone for MLModelError

fn clone(&self) -> MLModelError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MLModelError

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

Formats the value using the given formatter.

impl Encode for MLModelError

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for MLModelError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for MLModelError

fn cmp(&self, other: &MLModelError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MLModelError

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

fn partial_cmp(&self, other: &MLModelError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RefEncode for MLModelError

const ENCODING_REF: Encoding
